ISAOA and ATIMA Explained

Why these abbreviations exist

Mortgage loans and their servicing rights are bought and sold routinely. A property policy issued at closing may run for a full year, and the borrower may renew it for decades. Without some way to carry the lender's rights forward, every sale would leave a gap until the policy was endorsed. ISAOA closes that gap. ATIMA addresses a different issue: making sure the lender is paid only what it is owed, not the full claim amount. For the clause as a whole, start with what a mortgagee clause is.

ISAOA: its successors and/or assigns

What it means

"Successors" are entities that take over the lender by merger or acquisition. "Assigns" are parties to whom the lender transfers the loan or its servicing. Adding ISAOA after the lender's name tells the insurer that the mortgagee interest belongs to the named lender *and* to whoever steps into its shoes.

What it does in practice

• Keeps the protection continuous after a transfer. If ABC Bank sells servicing to another company, the existing designation still describes a party with rights under the policy until the insurer updates its records.
• Matches what investors require. Fannie Mae's Selling Guide (B7-3-08) requires the lender's name "followed by the phrase 'its successors and/or assigns,'" and mailing address, or the servicer's name with the same phrase when the lender is not the servicer. Freddie Mac's Guide (Section 4703.6) uses "(name of Seller/Servicer), its successors and assigns."

Notice the small wording difference: Fannie Mae's text says "and/or," Freddie Mac's says "and." Both convey the same idea. Use whatever wording the lender or servicer gives you.

What ISAOA does not do

ISAOA does not route mail or claim checks to a new servicer automatically. The insurer still sends cancellation notices, renewal bills, and loss drafts to the name and address on file. That is why Fannie Mae's Servicing Guide (F-1-11) requires the transferor or transferee servicer to ask property and flood insurers for an endorsement substituting the new servicer in the mortgagee clause and changing the premium billing address. See how to add or change a mortgagee for the mechanics.

ATIMA: as their interests may appear

What it means

ATIMA says the lender is paid to the extent of its interest in the property, not more. For a mortgage lender, that interest is generally the outstanding debt secured by the property.

A simple illustration

Suppose a covered fire causes $90,000 of damage to a house, and the remaining mortgage balance is $60,000. ATIMA language signals that the lender's claim to the money is capped at its $60,000 interest; it cannot claim the full $90,000. In practice, insurers commonly issue building-loss checks payable jointly to the homeowner and the servicer, and the servicer's loss draft process (including releasing funds for repairs) governs how the money is disbursed. Investor and FHA rules address how servicers handle those proceeds; for example, HUD Handbook 4000.1 requires FHA servicers to expedite release of insurance proceeds for needed repairs after approving a viable repair plan.

Is ATIMA redundant?

Partly. The ISO homeowners form already says building losses are paid "to the mortgagee and you, as interests appear," and the ISO commercial Loss Payable Provisions endorsement (CP 12 18) states that the insurer will not pay any loss payee more than its financial interest in the covered property. So the "interests" principle is often built into the policy itself. Many lenders still include ATIMA in their clause because it states the principle on the face of the declarations page.

Is ATIMA required?

Fannie Mae's and Freddie Mac's single-family mortgagee clause language requires successor wording but does not mention ATIMA. Some programs do include it in their model clauses: Fannie Mae's multifamily guide and HUD's Section 232 (residential care facility) handbook both show example clauses that combine successor language with "as their interest may appear," and at least one state housing finance agency, the Connecticut Housing Finance Authority, includes it in its required format. The practical rule: include ATIMA when the lender's instructions include it, and do not add or remove it on your own.

How the abbreviations are written

Lenders format these differently, and insurers' systems have their own field limits. You may see:

• spelled out: "its successors and/or assigns, as their interests may appear"
• abbreviated together: "ISAOA/ATIMA"
• separated: "ISAOA ATIMA" or "ISAOA, ATIMA"
• successor language only: "ISAOA"

A generic format example only (not a real lender or address):

ABC Bank, N.A. ISAOA/ATIMA
P.O. Box 0000
City, ST 00000

Spelled-out and abbreviated forms carry the same meaning. What matters more is that the lender name, address, and loan number are correct. Members can check a specific lender's current preferred format on its lender page via search; each listing is marked Verified (confirmed against the lender's or servicer's own primary source, with the check date shown) or Pending Verification.

Related terms you will see

• Loss payee: a party paid for loss to specific property, often personal property, vehicles, or equipment. Not interchangeable with a mortgagee. See loss payee vs. mortgagee vs. additional insured.
• "Beneficiary": Freddie Mac notes that in deed-of-trust jurisdictions the designation may read "(name of Seller/Servicer), its successors and assigns, beneficiary."
• "In care of" (c/o): used when an investor or agency must be named but correspondence should go to the servicer, as in Fannie Mae's "Fannie Mae, in care of (servicer)" format.

Common mistakes

• Treating ISAOA as a forwarding instruction. It preserves rights; it does not update the address. Request an endorsement after a servicing transfer.
• Adding ATIMA to a clause the lender gave without it (or stripping it out to fit a field). Enter what the lender specified; if a system truncates the text, note it and confirm with the carrier.
• Putting ISAOA after the wrong name. It belongs after the lender or servicer being named, not after "c/o" text or the loan number.
• Assuming ISAOA covers a refinance. A refinance creates a new loan, often with a new lender. The old lender is not a "successor" of the new one; the new lender's clause must be added.
• Using these terms on liability coverage. A mortgagee clause applies to property coverage. Lenders that need liability protection on commercial loans ask for additional insured status instead.

Frequently asked questions

What does ISAOA stand for?

ISAOA stands for "its successors and/or assigns." Placed after the lender's or servicer's name in a mortgagee clause, it extends the lender's rights under the policy to any company that later acquires the lender or takes over the loan or its servicing.

What does ATIMA stand for?

ATIMA stands for "as their interests may appear." It means the lender is entitled to claim payment only up to its actual insurable interest in the property, which for a mortgage is generally the unpaid balance of the loan.

Do I have to use ISAOA on a homeowners policy?

For loans sold to Fannie Mae or Freddie Mac, the mortgagee clause must include successor language. Fannie Mae's guide uses "its successors and/or assigns," and Freddie Mac's uses "its successors and assigns." Most other lenders also include it. Follow the exact wording in the lender's instructions.

Is it okay to spell out ISAOA and ATIMA instead of abbreviating them?

Yes. The abbreviations and the spelled-out phrases mean the same thing. Use the form the lender requests, and if a carrier system's character limit forces abbreviation, the standard abbreviations are widely recognized.

Does ISAOA mean I never need to update the mortgagee after a servicing transfer?

No. ISAOA keeps the original designation legally effective, but notices, bills, and claim checks still go to the name and address on file. Servicers are expected to request an endorsement naming the new servicer, and Fannie Mae's Servicing Guide requires it for loans it owns.
