To write AKA in a legal document, put the person’s legal name first, then the designation, then the alternate name: “Jane Alice Conrad a/k/a Jane Doe.” The forward-slash form a/k/a is the format you’ll see most often in court filings, deeds, and contracts, though “AKA,” “a.k.a.,” and the spelled-out “also known as” are all accepted. The abbreviation style you choose matters far less than picking the right designation for the situation (AKA, FKA, NKA, or DBA) and placing it where the document expects it.
Which Abbreviation to Use
Four forms circulate in legal writing, and no court will reject a filing over which one you picked:
- a/k/a is standard in court pleadings and case captions.
- AKA or aka shows up in contracts, affidavits, and less formal legal documents.
- a.k.a. is the grammatical form with periods. Some style guides prefer it; courts use it less.
- “also known as” spelled out is the safest choice when you’re not sure what a particular court prefers, and it’s common in wills and trusts where clarity for non-lawyers matters.
Pick one form and use it consistently through the document. Mixing “a/k/a” and “AKA” in the same instrument looks careless and can raise questions during review.
AKA, FKA, NKA, or DBA — Pick the Right One
Defaulting to “AKA” for every name variation is the most common mistake. Legal documents distinguish between names that are both current, names that used to apply, names that now apply, and business names. Using the wrong designation muddies the record and can cause problems at notarization.
AKA (Also Known As)
Use AKA when two names both currently refer to the same person: nicknames, name variations, maiden names still in use, or slight differences between how a name appears on different documents. Someone whose driver’s license reads “John Doe” but whose mortgage says “John A. Doe” would sign as “John A. Doe a/k/a John Doe.” Both names are current and valid.
FKA (Formerly Known As)
FKA fits when the document uses the person’s new name but their identification still shows the old one. Someone who recently married and changed her name to Jane Conrad Doe, but hasn’t updated her ID from Jane Alice Conrad, would sign: “Jane Conrad Doe, FKA Jane Alice Conrad.” The old name is no longer in active use.
NKA (Now Known As)
NKA is the mirror of FKA. Use it when the document references the person’s former name but their ID reflects the new one: “Jane Alice Conrad, NKA Jane Conrad Doe.” Both FKA and NKA generally require evidence of the legal name change — a marriage certificate, divorce decree, or court order.
DBA (Doing Business As)
DBA is the business equivalent. It applies when a person or company operates under a name different from their legal name. A sole proprietor named Maria Lopez running a bakery called “Sunrise Sweets” would write “Maria Lopez d/b/a Sunrise Sweets” in a contract. Filing a DBA does not create a new business entity or provide liability protection; it puts the public on notice about who owns the business.1Wolters Kluwer. What Is a DBA A trade name is not a personal alias, so DBA rather than AKA is the correct designation.
Where the AKA Goes
Placement follows the same rule everywhere: legal name first, designation, then the alternate name. The location within the document depends on document type.
Court Filings and Case Captions
In lawsuits and criminal cases, aliases go in the case caption — the heading identifying the parties. Federal rules require every pleading’s title to name all parties.2Legal Information Institute. Federal Rules of Civil Procedure Rule 10 – Form of Pleadings A caption typically reads “John Doe, a/k/a Jonathan Smith” so the record ties both identities together. In criminal filings, prosecutors list all known aliases so charges attach to the right person.
Contracts
In contracts, the designation appears in the introductory paragraph identifying the parties. A typical preamble reads: “This agreement is entered into by Maria Lopez, a/k/a Maria L. Gonzalez (‘Seller’)…” Doing this up front keeps the contract enforceable regardless of which version of the name shows up in related documents. Swap in “d/b/a” when a business trade name is involved.
Wills, Trusts, and Estate Documents
Estate documents should list every name the person has used, especially for assets titled under different names. A will might open: “I, Jane Conrad Doe, also known as Jane Alice Conrad, hereby declare this to be my Last Will and Testament.” Spelling out “also known as” rather than abbreviating is common here because probate courts and beneficiaries reviewing the document years later benefit from plain language.
Form I-9 and Employment Records
Federal employment eligibility verification asks for prior names directly. The Form I-9 instructions direct employees to enter their current legal name along with any last names previously used.3U.S. Citizenship and Immigration Services. Instructions for Form I-9, Employment Eligibility Verification The field captures maiden names, names from prior marriages, and any other surname used. It does the same identity-linking work as AKA does elsewhere.
Signing and Notarizing With an AKA
Your signature should match the names referenced in the body of the document. If a deed identifies you as “John A. Doe a/k/a John Doe,” sign as “John A. Doe a/k/a John Doe.” Signing with only one version when the document uses both can raise questions about whether the signer is the person named.
Notaries verify identity by comparing the name on the document to the name on your government-issued ID. When those don’t match exactly, the notary needs to bridge the gap. For a small variation like a middle initial on the document but not the ID, a notary will usually accept the AKA after checking a second form of identification. For a full name change, the notary will look for official proof of the transition (marriage certificate, divorce decree, or court order), and the notarial certificate will reflect the name as signed, including the AKA, FKA, or NKA designation.
Property Records and the “One and the Same Person” Affidavit
Property transactions are where AKA issues surface most often and cost the most to fix. Every document in a property’s chain of title — deeds, mortgages, liens, satisfactions — must clearly point to the same owner. If you bought property as “Jane Conrad” and later sold it as “Jane Doe” after marriage, a title examiner will flag the gap because nothing in the record proves those are the same person.
The standard fix is an affidavit of identity, often called a “one and the same person” affidavit. It’s a sworn, notarized statement declaring that the different names in the property records all refer to you. The affidavit typically includes your full legal name, date of birth, every name variation appearing in the chain of title, and a clear statement that all the listed names belong to a single individual. Once notarized, it gets recorded in the land records alongside the deed, permanently linking the names for future searches.
Title companies routinely require this affidavit before issuing title insurance. If you’re selling or refinancing property and your name has changed since you acquired it, expect the closing attorney or title company to ask for one. Having it ready before closing avoids last-minute delays.
What Happens if You Leave the AKA Out
Omitting an alias rarely voids a document, but it creates friction that ranges from inconvenient to expensive.
In probate, a missing alias can delay asset distribution. If a decedent held bank accounts under one name and real property under another, and the probate petition only references one, financial institutions may refuse to release funds until the estate representative gets a court order linking the names. Beneficiaries wait longer and legal fees climb.
In contract enforcement, a missing AKA adds a step. If someone signed as “John Smith” but their legal name is “Juan Hernandez-Smith,” the other party may have to prove both names belong to the same person before a court will enforce the agreement. Debt collectors run into this constantly when a debtor’s records are scattered across unlinked names. These problems are all solvable. They just cost more time and money than getting the designation right the first time.
