Three platforms, three answers to who owns the ad account. One documents that it can never be transferred. Run this audit before you say you are leaving.
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 You can be granted access indefinitely, and that access can be withdrawn.
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.
Implement your own tag, run both in parallel, then unlink. The wrong order costs you the measurement your bidding runs on. Source : Google Ads unlinking documentation (2026)
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.
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.
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.
Whichever business portfolio created or claimed it. Meta states that an account created in a portfolio will permanently be part of it and cannot be deleted or transferred from it. Sharing access is the only alternative.
Can my agency transfer the Meta account to me?
No. The documentation is explicit that it cannot be transferred between portfolios. They can grant your portfolio access to it, but ownership stays where it was created or claimed.
What about the pixel?
Same rule. Meta states you cannot delete a dataset or transfer it to another business portfolio, and directs you to add partners or people to it instead.
Is Google Ads different?
Structurally yes. Google states that manager account owners do not take data ownership or administrative rights away from client accounts, that the client account still owns its data, and that it can unlink at any time.
Do I lose anything by unlinking from a manager account?
The account keeps its campaign history and features. But if you were using the manager's shared remarketing tag or cross-account conversion tag, those lists stop populating and that tag stops recording conversions after unlinking.
What if nobody can access my old account?
On Google there is a documented recovery route requiring proof of ownership, usable even when no active administrator exists. On LinkedIn the documentation says you might need to create a new ad account.
Can I move a LinkedIn ad account between Business Managers?
No procedure is documented. LinkedIn states only one Business Manager can own an ad account and that access to another organisation's account comes through a partnership, without describing any transfer.
What is the single most important thing to check?
Which business portfolio owns your Meta ad account and dataset. That answer may already be permanent, and everything else in a transition plan depends on it.
