On one platform, the answer to “can I take my ad account with me” is documented as no, permanently. On another, there is a recovery procedure even when nobody has access. On the third, the documentation says you may need to start again.

Those three positions are all published, they are all different, and almost nobody checks which applies to them until they are already trying to leave.

This page gives each platform’s position with the wording, then the audit to run before you tell anyone you are switching.

The social platform: permanent, and it says so

The clearest statement of the three, and the least widely known.

On ad accounts, verbatim. If you create a new ad account in a business portfolio, it will permanently be a part of that portfolio. This means the ad account cannot be deleted or transferred from the portfolio.

On accounts you add later, verbatim. Adding an existing ad account to a business portfolio may permanently move it into the portfolio, meaning it cannot be deleted or transferred to another portfolio.

The constraint that follows. An ad account can only be in one business portfolio.

What is available instead, verbatim. Ad accounts can be shared. Requesting to share leaves the account in the owner’s portfolio while access is granted to yours, and the owner must approve.

On the dataset carrying your pixel events, verbatim. Remember that you cannot delete a dataset or transfer it to another business portfolio. The documentation directs you to add partners or people to it instead.

On audiences, verbatim. You can share a custom audience with another ad account. But if you delete the audience from your account, it will also be deleted from the recipient account. And if an audience is shared with you, you cannot share that audience with another ad account.

What all of that adds up to. If your agency created your ad account and your dataset inside its own portfolio, you will never own them. You can be granted access indefinitely, and that access can be withdrawn.

Documented ownership and transfer positions for advertising accounts across three platformsComparison of the documented ownership and transfer positions for advertising accounts across the three major advertising platforms. The social platform states that an advertising account created in a business portfolio will permanently be part of that portfolio and cannot be deleted or transferred from it, that adding an existing account may permanently move it into the portfolio with the same consequence, and that an advertising account can only exist in one business portfolio; sharing is offered as the alternative, under which the account remains in the owner’s portfolio while access is granted elsewhere subject to the owner’s approval. The same platform applies an identical restriction to datasets carrying pixel events, stating that a dataset cannot be deleted or transferred to another business portfolio and directing advertisers to add partners or people to it instead. Custom audiences on that platform may be shared but not transferred, and deletion by the owner removes the audience from recipient accounts, while an audience shared with a recipient cannot be shared onward by that recipient. The search platform takes the opposite structural position, stating that manager account owners have full administrative and data access privileges but do not take data ownership or administrative rights away from client accounts, that the client account still owns its data and retains the ability to remove ownership access by unlinking, and that an individual account which unlinks will not lose its campaign history or access to platform features; it additionally documents a recovery procedure requiring proof of ownership, usable even where no active administrator remains on the account. The professional network states that only one business manager can own an advertising account and that access to another organisation’s accounts comes through a partnership, but documents no transfer procedure, and states that where no contactable person retains access to an existing account a new advertising account may need to be created.”Can I take my account with me?”Social platform: no, permanently”it will permanently be a part of that portfolio… can’t be deleted or transferred from the portfolio”Dataset: “you can’t delete a dataset or transfer it to another business portfolio”Audiences shareable, never transferable. Owner deletion removes them from recipients too.Search platform: the client always owns its dataManagers “do not take data ownership or administrative rights away from client accounts""The client account still owns its data and has the ability to remove ownership access by unlinking.”Plus a documented recovery route on proof of ownership, even with no active admin.Professional network: no route documented”Only one Business Manager can own an ad account.” Access to another’s comes via partnership.”you might need to create a new ad account” if nobody with access is reachable.Three published positions, all different. Check which one applies to you before you give notice.
One says permanently no. One says the client always owns its data. One documents no route at all. Source : Platform documentation; social platform pages via web archive (2026)

The search platform protects you, with one exception

Structurally the friendliest of the three, and the exception is worth knowing precisely.

On ownership, verbatim. Owners have full administrative access and data access privileges, but do not take data ownership or administrative rights away from client accounts. The client account still owns its data and has the ability to remove ownership access by unlinking.

On who can do what, verbatim. Users of the client account do not have permission to transfer ownership, but can always unlink a manager with ownership. After an owner manager is unlinked, the client account can turn on ownership for a different manager.

On linking an existing account, verbatim. When you link your manager account to an existing account, the original client account remains unchanged and its account history remains intact.

On unlinking, verbatim. An individual account can unlink from a manager account, and will not lose its own campaign history or access to any features.

The exception, and it is real. When you unlink an account that was using the manager account’s shared remarketing tag or shared remarketing lists, the lists relying on that tag will no longer populate. And if the account was using the manager’s cross-account conversion tracking tag, that tag will no longer record conversions after unlinking.

What that means in practice. The account is yours. The tracking may not be. If your agency implemented conversion tracking through its own manager-level tag, unlinking stops your conversion measurement, and rebuilding it starts your bidding data from nothing.

The recovery route, verbatim. If you cannot access your account because the original manager has left your organisation, you can use the account access request form, providing proof of account ownership which is validated by the support team. This works even where there are no active administrators.

And the one recommendation the platform does make. That if your account has only one administrator, you may lose access to your tags if that user becomes unavailable, and adding at least one additional administrator may help ensure uninterrupted tag management.

The professional network has no documented exit

Not a prohibition, an absence, and the practical effect is similar.

On ownership, verbatim. Only one Business Manager can own an ad account. If another organisation owns accounts you need to work on, you can request access, or create a partnership so they can share accounts with you.

What is not documented. Any procedure for transferring ownership of an ad account between Business Managers. The documentation is silent rather than prohibitive, which is a distinction worth preserving.

The sentence that matters most, verbatim. If you are no longer in contact with a person who has access to the existing account, you might need to create a new ad account.

Why that is the harshest position of the three. The search platform documents recovery on proof of ownership. This one documents starting over.

Who holds the keys by default, verbatim. Each ad account must have a billing admin, and the person who creates the ads account is automatically assigned as the billing admin.

And what a partner can do, documented. A shared ad account can be unshared by the owning partner at any time, at which point access disappears.

The recommendation the platform does give. Assign at least two admins in Business Manager to help ensure there is always an active admin, and limit admins to senior employees.

Recovery routes available on each advertising platform when account access is lostComparison of the recovery routes documented by each advertising platform for situations in which an advertiser has lost access to an advertising account. The search platform documents a formal recovery procedure: where an advertiser cannot access an account because the original manager has left the organisation, an account access request form may be used to request a permission change, and this route remains available in cases where no active administrators exist on the account, requiring the advertiser to provide proof of account ownership which is validated by the support team before access is granted. The same platform additionally notes that where an account has only a single administrator, the advertiser may lose access to its tags should that user become unavailable, and recommends adding at least one further administrator to help ensure uninterrupted tag management. The social platform offers no ownership recovery because ownership cannot move: an account created or claimed within a business portfolio remains permanently within it, so the only available position for an advertiser whose agency owns the account is indefinite shared access which the owner may withdraw. The professional network documents neither a transfer procedure nor a recovery procedure, and states directly that where an advertiser is no longer in contact with a person holding access to the existing account, that advertiser might need to create a new advertising account, which constitutes the harshest documented position of the three since it entails losing campaign history, audiences and tracking continuity entirely. That platform also documents that each advertising account must have a billing administrator and that the person who creates the account is automatically assigned that role, and recommends assigning at least two administrators in its business manager to ensure an active administrator always exists.If access is lost, where does each leave you?Search platformA documented routeAccess request form, withproof of ownership.Works even with no activeadministrator on the account.Advice: keep two admins.Social platformNo recovery, because notransfer existsOwnership cannot move.

The consequence of unlinking while dependent on a manager account’s shared tracking tagsExplanation of the consequence of unlinking an advertising account from a manager account while depending on that manager’s shared tracking tags, and the correct sequence to avoid it. The search platform documents that an individual account which unlinks from a manager account will not lose its own campaign history or access to any platform features, which means the account itself and its data are preserved. However, the same documentation records an exception: where an account being unlinked was using the manager account’s remarketing tag or any shared remarketing lists, the lists relying on that shared tag will no longer populate, and where the account was using the manager’s cross-account conversion tracking tag, that tag will no longer record conversions for clicks occurring after the account was unlinked. The practical consequence is that the advertising account remains the advertiser’s property while the measurement infrastructure may not, and since automated bidding strategies depend on conversion data, losing conversion recording at the moment of unlinking removes the input those strategies require. The correct sequence is therefore to implement the advertiser’s own conversion tag first, run both the new tag and the existing manager tag in parallel for long enough to confirm the new tag is recording correctly, and only then unlink the manager account. Performing these steps in the reverse order, which is what happens when an unlink occurs first and tracking is rebuilt afterwards, costs the advertiser the conversion measurement on which bidding depends, during precisely the period when a new agency relationship is being evaluated.The question that decides unlink dayWhat survives, verbatimAn account that unlinks “won’t lose its own account campaign history or access to any features.”What does not, verbatimUsing the manager’s remarketing tag: “the lists that rely on the shared tag will no longer populate”Using its cross-account conversion tag: it “will no longer record conversions” after the unlink.1.

The audit, before you say anything

Ten checks. Run them before giving notice, because cooperation is easier to obtain while the relationship is intact.

One: which portfolio owns the social ad account. Open business settings and find the owning portfolio. If it is not yours, that is now a permanent fact and the rest of your plan has to accommodate it.

Two: which portfolio owns the dataset. Same question, separate answer, same permanence.

Three: whether you hold full control or partial access. On a shared asset, partial access means you can only assign permissions for tasks your business was assigned. That limits what you can hand to a successor.

Four: whether your search account sits under someone’s manager account, and whether that manager has ownership. Ownership enabled by you is revocable by you. Linking alone does not grant it.

Five: whose conversion tag you are using. Your own, or the manager’s cross-account tag. This is the single most consequential technical question in the audit.

Six: whose remarketing tag populates your lists. If it is the manager’s shared tag, unlinking stops the lists.

Seven: who the billing admin is on the professional network. Whoever created the account holds it by default, and it may not be you.

Eight: how many administrators exist on each account. If the answer is one, and that one is at the agency, fix it today regardless of whether you are switching.

Nine: whether audiences were built in your account or shared into it. Shared audiences cannot be re-shared onward and disappear if the owner deletes them.

Ten: export everything before any of this becomes contentious. Campaign history, conversion history, search terms, audience definitions, and reporting at the finest granularity available.

A ten-point advertising account ownership audit and which findings are irreversibleA ten-point audit of advertising account ownership to be conducted before an advertiser gives notice to an incumbent agency, since cooperation is more readily obtained while the relationship remains intact, together with an indication of which findings are already irreversible. The first check establishes which business portfolio owns the social advertising account, an answer which if it is not the advertiser’s own portfolio constitutes a permanent fact requiring the remainder of the transition plan to accommodate it. The second check establishes which portfolio owns the dataset carrying pixel events, a separate answer subject to the same permanence. The third check establishes whether the advertiser holds full control or only partial access to shared assets, since partial access permits assigning permissions only for tasks the business was itself assigned, limiting what can be handed to a successor. The fourth check establishes whether the search account sits beneath a manager account and whether that manager holds ownership, noting that ownership enabled by the client is revocable by the client and that linking alone does not confer it. The fifth check establishes whose conversion tag is in use, the advertiser’s own or the manager’s cross-account tag, which is the single most consequential technical question in the audit. The sixth check establishes whose remarketing tag populates the advertiser’s lists, since a manager’s shared tag ceases populating them on unlinking. The seventh check establishes who holds the billing administrator role on the professional network, which defaults to whoever created the account. The eighth check counts administrators on each account, with a single administrator located at the agency requiring immediate correction regardless of any transition. The ninth check establishes whether audiences were built within the advertiser’s account or shared into it, since shared audiences cannot be re-shared onward and disappear if the owner deletes them. The tenth check is to export campaign history, conversion history, search terms, audience definitions and finest-granularity reporting before any of this becomes contentious.Ten checks, run them before you give noticeThese two may already be permanent1.

What to do with each answer

Six outcomes, and what each one costs.

Your portfolio owns everything. Nothing to do. Grant access, revoke it later, move on.

Their portfolio owns the ad account but you have full control. Workable indefinitely, and it is not ownership. Negotiate continuity of access in writing as part of any exit, and know that it depends on their cooperation.

Their portfolio owns the dataset. The most expensive version. A new dataset starts empty, and the platform documentation does not describe what becomes of the event history you cannot reach. Plan for a rebuilding period.

You are on the manager’s conversion tag. Implement your own tag before you unlink, run both in parallel long enough to confirm the new one records, then unlink. Doing this in the wrong order costs you the measurement your bidding depends on.

One administrator, at the agency. Fix it this week whether or not you are leaving. This is an availability risk, not just a negotiating one.

Nobody reachable has access at all. On the search platform, use the documented recovery route with proof of ownership. On the professional network, the documentation says you may need to create a new account, so budget for starting the history again.

Six possible outcomes of an advertising account ownership audit and the cost of eachThe six possible outcomes of an advertising account ownership audit together with the practical cost each imposes on the advertiser. Where the advertiser’s own business portfolio owns everything, no action is required: access can be granted to an agency and revoked later without consequence. Where the agency’s portfolio owns the advertising account but the advertiser holds full control, the arrangement is workable indefinitely but does not constitute ownership, so continuity of access should be negotiated in writing as part of any exit and remains dependent on the agency’s cooperation. Where the agency’s portfolio owns the dataset carrying pixel events, this is the most expensive outcome, since a new dataset begins empty and the platform documentation does not describe what becomes of event history the advertiser cannot reach, requiring a planned rebuilding period. Where the advertiser is using the manager account’s conversion tag, the correct response is to implement an independent tag, operate both in parallel until the new tag is confirmed to be recording, and only then unlink, since performing these steps in the reverse order costs the conversion measurement on which automated bidding depends. Where only a single administrator exists and that administrator is at the agency, this should be corrected within the week regardless of whether a transition is planned, because it constitutes an availability risk rather than merely a negotiating one. Where nobody reachable holds access at all, the search platform offers a documented recovery route requiring proof of ownership, while the professional network’s documentation states that a new advertising account may need to be created, meaning the advertiser should budget for rebuilding the account history from nothing.Six outcomes, and what each costsWhat the audit foundWhat it costsYour portfolio owns everythingNothing.

Where to go next

You are planning the handover itself. Changing agency without breaking campaigns.

You are choosing the replacement. Choosing a B2B acquisition agency.

You want to set reporting expectations. What agency reporting must contain.

You want to know how long to give them. How long before judging an agency.

You are considering bringing it in-house. In-house vs outsourced media buying.

You want the account structure itself. Meta ads account structure.

In short

  • A Meta ad account created in a portfolio cannot be deleted or transferred from it. Adding an existing one may permanently move it.
  • The same applies to the dataset: you cannot delete it or transfer it to another portfolio.
  • Audiences can be shared, never transferred, and deleting yours removes it from recipients too.
  • Google takes the opposite position: managers do not take data ownership away, the client still owns its data, and unlinking preserves campaign history.
  • With one real exception: the manager’s shared remarketing tag and cross-account conversion tag stop working for you on unlinking.
  • Google documents a recovery route on proof of ownership, usable with no active administrator.
  • LinkedIn documents neither transfer nor recovery, and says you might need to create a new ad account.
  • Whoever creates the account holds the billing admin role on that platform by default.
