You can change your last name after a divorce to almost anything you want, but how you get there depends on the name you pick. Restoring a name you used before the marriage can happen inside the divorce case itself. Choosing a surname you’ve never legally held requires a separate name change petition. Courts approve most requests, but they will refuse names chosen to defraud or names their databases cannot process.
Restoring a Former Name Through the Divorce
The simplest route is asking the court to restore a name you held before the marriage. Most states let you include this request directly in your divorce paperwork, so by the time the judge signs the final decree, your former name is legally restored without a separate case.1USAGov.

“Former name” is not limited to your birth surname. If you were married before and took that spouse’s name, you can generally restore that name through the decree as well. The requirement is that you actually used the name legally at some point.
A name restoration in a divorce decree does not expire. If a judge signed your decree years ago restoring your maiden name and you never updated your records, that order is still valid. The Social Security Administration will still accept it as proof of your legal name.3Social Security Administration.

When You Need a Separate Name Change Petition
If you want a surname you’ve never legally held, the divorce case cannot deliver it. Judges treat name restoration as part of wrapping up the marriage, and granting a brand-new identity falls outside that scope. Writing a preferred new name into a divorce settlement will not make it your legal name for identification purposes.
You will need to file a legal name change petition, the same process any adult can use regardless of marital status. This is also the route to take if your divorce decree did not restore your former name because you did not ask at the time. There is no deadline for filing.
How the Name Change Petition Works
The standalone petition follows the same general shape everywhere in the country, though details vary by state.
Filing
You file a document typically called a Petition for Change of Name with the court in the county where you live. It asks for your current legal name, the name you want, and your reason. Most states require you to have lived in the state for at least six months before filing; some require up to a year.
Publication and Hearing
Many states still require you to publish notice of your intended name change in a local newspaper for several consecutive weeks before a hearing, giving creditors or others a chance to object. Publication usually costs under $100. A growing number of states have eliminated the publication requirement, and others waive it when the petitioner has safety concerns such as domestic violence.1USAGov. How to Change Your Name and What Government Agencies to Notify
Some courts hold a brief hearing where a judge asks a few questions and rules on the spot. Others grant the change on paper when nobody objects. Either way, an approved petition produces a court order that serves as your legal proof of the new name.
Costs and Timeline
Court filing fees range widely. A few states charge under $100. California and Florida charge over $400. Most states fall between $150 and $350. Add newspaper publication in states that still require it, and total costs typically run between $150 and $550.
From filing to final order, most states process a name change in two to ten weeks. States with heavier caseloads or longer publication windows can take three to five months. A background check requirement, where applicable, can add a week to a month.
Names Courts Will Not Approve
Judges approve most petitions, but a request that crosses certain lines will be denied. The biggest one is fraud: you cannot change your name to dodge debts, avoid a criminal record, evade child support, or mislead someone for financial gain.
Judges also deny names that are obscene or offensive, names adopted to trade on a celebrity’s reputation, and names containing numerals, symbols, or characters that government databases cannot process. No federal statute lists these prohibitions; they are broad principles applied by judges using their discretion. The clearest path to approval is a straightforward request with a genuine reason.
If You Have a Criminal Record
A criminal history does not automatically bar a name change, but it complicates the process. Several states require a criminal background check as part of the petition, and some create a legal presumption that a person with a felony record is seeking the change for fraudulent reasons. You can overcome that presumption by showing a legitimate purpose, but the burden is on you.
Registered sex offenders face the tightest restrictions. Some states flatly prohibit name changes for people on the registry; others allow them only with added notification to law enforcement. Disclose any criminal history upfront in the petition. Trying to hide it is the fastest route to denial.
Updating Your Records
A court order does not automatically update the databases that identify you. You have to contact each agency, and the order matters. Start with the Social Security Administration, because other agencies verify identity against SSA records. You will need Form SS-5, your divorce decree or court order, and proof of identity. The SSA does not charge a fee.4Social Security Administration. Application for Social Security Card
Once your Social Security record reflects the new name, work through the rest: driver’s license, passport, voter registration, banks and credit cards, employer and payroll, insurance and healthcare providers, the county property tax office if you own a home, and the post office.1USAGov. How to Change Your Name and What Government Agencies to Notify
Tax filing follows the same logic. The IRS matches the name and Social Security number on your return against SSA records, so a mismatch can delay your refund.5Internal Revenue Service. Name Changes and Social Security Number Matching Issues If you have not updated your SSA record by tax time, file under your former name rather than your new one. There is no separate form to notify the IRS; the agency pulls the update from SSA automatically.
What Doesn’t Change: Your Children’s Names
A parent’s name change does not carry over to a child. Even if your decree restores your maiden name, your children keep whatever surname appears on their birth certificates. Changing a child’s last name requires a separate petition on the child’s behalf, and courts apply a best-interest-of-the-child standard rather than the looser standard for adults. The other parent generally must be notified and has the right to object. When both parents agree, courts usually grant the change; when they disagree, the judge decides based on the child’s welfare.
