Short answer
Mortgage foreclosure surplus comes from a sale to pay a mortgage. Tax sale overages come from a sale to pay unpaid property taxes. Unclaimed property is money a state holds after the original holder could not find the owner. Each has its own claim process.
| Mortgage foreclosure surplus | Tax sale overages | State unclaimed property | |
|---|---|---|---|
| Where it comes from | Sale after a mortgage or deed of trust default | Sale after unpaid property taxes | Money turned over to the state, which can include old surplus |
| Who usually holds it | Court clerk or foreclosure trustee | County tax office, treasurer or court | State treasurer or comptroller |
| Rules come from | State foreclosure statutes and court rules | State tax sale laws | State unclaimed property laws |
| How to claim | Claim, motion or petition in the foreclosure case | Application to the tax office or court | Claim through the state's unclaimed property program |
Why the difference matters
Each kind of money is held by a different office, with different deadlines, forms and rules for who may help you. Sending a mortgage surplus claim to a tax office, or the reverse, can waste weeks.
The categories can also connect. In Florida, mortgage foreclosure surplus not paid out within a year of the sale is presumed unclaimed and sent to the state's unclaimed property program, where the owner of record or a deceased owner's beneficiary can still claim it.1
