What to keep in a fireproof safe, and what belongs somewhere else

The short version: three places

Most households end up using some mix of three places for their important papers:

A fire-resistant safe or box at home for anything you or your family might need quickly, at any hour.
A bank safe-deposit box for originals that are hard to replace and rarely needed in a hurry.
Your attorney's office for signed estate documents, if your attorney offers to keep the originals.

There's no single right split. What matters is that each document has one home, and that two people you trust could find it without you.

What "fireproof" usually means

Most home safes and document boxes are fire-resistant rather than fireproof. They're tested to keep the inside below a set temperature for a set time, and the right rating depends on what you're storing. Under the UL 72 standard, for example, a Class 350 rating is meant for paper records, while Classes 150 and 125 are meant for paper plus things like photographic records and computer media (UL 72 summary). That matters if you plan to keep a flash drive in there.

Check whether it's rated for water too. A box that survives a fire can still let in the water used to put it out. FEMA suggests keeping a binder of important papers in a fireproof and waterproof box or safe at home, next to your emergency kit, so you can grab both quickly.

What belongs in a safe at home

The home safe's strength is access. Use it for things you might need on a weekend, in an evacuation, or if someone is suddenly in the hospital:

Passports, and birth certificates for everyone in the household
Social Security cards, which you shouldn't carry day to day
Copies of health-care powers of attorney and advance directives, and a copy of any financial power of attorney
Copies of insurance policies, with the claims phone numbers
Vehicle titles, and a copy of the deed
A copy of your will, with a note saying where the original is
A medication list for each person who takes something regularly
A flash drive with scanned copies, if the box is rated for it
Your family file, or a note saying where it is

Social Security says to keep your card in a safe place and only bring it with you when absolutely necessary. Notice, too, how many of the items above are copies. The home safe often holds the working set, plus a note pointing to where each original lives.

What can go in a bank safe-deposit box

A safe-deposit box is well protected, and it's a reasonable home for originals you rarely touch: the original deed, savings bonds, a marriage certificate you can't easily replace, a coin collection. FEMA's financial preparedness guidance suggests storing papers like insurance policies, deeds and property records somewhere safe, such as a safe-deposit box away from home, and keeping copies in your disaster supplies kit.

Three things to know before you rely on one:

It isn't FDIC-insured. The FDIC lists safe-deposit boxes and their contents among the things deposit insurance doesn't cover. Ask your homeowners or renters insurer whether anything covers the contents.
It keeps bank hours. A passport in the bank does you no good on a Saturday.
Access after a death or a serious illness can be slow. Who can open the box depends on how it was rented, the bank's rules and state law. A family member with the key but no name on the rental agreement may be turned away. Ask your bank how it handles this, and write the answer down.

Because of that last point, think twice before making the bank box the only home for anything someone might need quickly, like a health-care power of attorney, funeral wishes or the original will.

What your attorney may hold

Some attorneys offer to keep the signed originals of the estate documents they prepare, such as a will or trust. If yours does, write down which attorney or firm has them and how to reach the office. Firms merge, move and close, so check that note once a year. Whether your originals should stay there, at home or somewhere else is a good question for the attorney who prepared them.

Why the original will needs a known address

Of everything in this guide, the will is where the original matters most. Courts generally work from the signed original, and some states set deadlines for getting it there after a death. In California, for example, whoever has the original must deposit it with the probate court clerk within 30 days (Fresno County Superior Court). If the original can't be found, it can cause real problems for your family, and how a court handles that depends on state law.

Some states also let you deposit an original will with a public office for safekeeping while you're alive. Texas allows it with the county clerk (Fort Bend County Clerk), and Delaware's Registers of Wills offer it too (Kent County Register of Wills). Rules and availability differ from state to state.

Wherever yours is, the person you named as executor should know. A copy in the home safe marked "Original is at the attorney's office" is worth more than it looks.

Originals and copies

A useful rule: keep originals together in one place, and copies of the most important ones somewhere else. If the house floods, the bank has the originals. If the bank is closed, the safe has the copies.

Certified copies aren't photocopies. Agencies that ask for a birth, marriage or death certificate usually mean one issued by a vital records office. The CDC keeps a list of state vital records offices if you need to order one.
Scans help, but they're still copies. Ready.gov suggests keeping electronic copies in a password-protected format on a flash drive or external hard drive in your fireproof and waterproof box, or using a secure cloud service. A scan won't replace an original where an original is required.

What not to keep in the safe

The only key or the only copy of the combination. It sounds obvious, and it happens all the time. Keep the key or combination somewhere separate, and make sure two people know where.
A list of passwords. A safe makes paper harder to steal, not impossible. A password manager with an emergency-access feature does this job better.
Your only grab-and-go copies, if the safe is bolted down. In an evacuation, a portable box beats a heavy safe. Our evacuation documents checklist covers what to grab.

Write down where, not what

The safe holds the papers. Your list says where they are.

Never write full Social Security numbers, full account or policy numbers, passwords, PINs, security answers or crypto seed phrases on your document list. Write where each original is kept, where the copies are, and the last four digits where that helps tell things apart.

A simple locator list does the work: the document, where the original is, where a copy is, and who else has one. Tell two people where the list is, and look at it once a year. Our guide to organizing important documents at home covers what to keep and for how long, and how long to keep financial records goes deeper on tax papers and statements.

A locator for every original

The Family File's Legal Documents Locator has a line for each document: whether you have one, the date signed, where the original is and which attorney has a copy. Money and Home & Property record where the safe-deposit box and the deed are. Last four digits only, never full numbers. Fillable PDF for $29, or a printed book with your family's name on the cover for $59.
