Memorandum of Contract in Real Estate
Also known as: Affidavit of Memorandum, Notice of Interest
A memorandum of contract is a short document recorded in the county deed records that publicly announces you hold a binding purchase agreement on a property. It puts later buyers on notice of your equitable interest and clouds title, so the seller can't quietly sell out from under you.
A memorandum of contract (also called an affidavit of memorandum or notice of interest) is a short document recorded in the county deed records that publicly announces a buyer holds a binding purchase agreement on a property, without disclosing the full contract terms. It is a notice of your equitable interest, not a lien and not ownership.

In DepthMemorandum of contract in real estate, explained
Think of a memorandum of contract as a flag you plant in the public record. It typically contains the names of the parties, a property description, the contract date, and a clause referencing the underlying purchase agreement. It does not reproduce your price or assignment terms, just enough to show a deal exists.
How and where it's recorded
The process is mechanical and cheap. Confirm your contract permits recording, draft the document, get it notarized before a notary public, then file it with the county recorder or clerk's office for a filing fee that often lands around $30. Some states add a notice step. In Texas, HB 4063 requires the filer to mail notice to the owner and respond within 45 days if the filing is challenged. Rules vary by state, so verify what your county requires before you file.
Why it protects the wholesaler
Once recorded, the memorandum puts subsequent purchasers on constructive notice of your equitable interest. That clouds title. A title company running a search will see your recorded interest and flag it, which makes it hard for the seller to close with another buyer until the cloud is cleared. It doesn't freeze the property in a legal sense, but in practice it stalls or kills a competing sale, and that is the leverage. The memorandum is leverage, not ownership.
The slander-of-title risk and when not to use it
This is where it gets dangerous. The line between protecting your interest and abusing the tool is a valid, enforceable contract. Recording a memorandum without one, or refusing to release it promptly once the deal is dead, can trigger a slander-of-title lawsuit, which targets publishing false information about property ownership in the public record. That exposes you to damages, attorney fee liability, fraudulent-lien claims, and in some states criminal liability for bad-faith filings. States are also moving against the tactic: Oklahoma banned clouding title via an affidavit of equitable interest to block a sale, effective November 1, 2025, and other states carry separate slander-of-title and wrongful-filing statutes. Treat these as examples, not a national rule, and confirm current law in your state. Recording a memorandum is not a safe default move, it is a legal step, so talk to a real estate attorney in your state before you record one.

A memorandum of contract sits next to a few ideas worth knowing: your equitable interest is the right it announces, the assignment of contract is how you usually exit the deal, and the title company is who surfaces the recorded notice during a search.
