Fortunately, Washington State law and online notary Washington allows you to complete this entire process 100% digitally. Teams that manage recurring notarizations can create a business account to streamline secure online document workflows.
So, without any further ado, let’s quickly discuss,
What Is a Seller Affidavit in Real Estate?
A seller affidavit is a sworn legal statement signed by the property owner. It guarantees to the buyer and the title company that the seller holds clear title to the property. It confirms there are no unrecorded liens, boundary disputes, or outstanding contractor bills attached to the house.
You must sign this document under oath. Because of this legal weight, a certified notary must verify your identity and witness your signature to make the document valid.

Seller Affidavits vs Other Common Legal Documents
During a real estate closing or legal dispute, you might encounter various types of sworn statements. It is important to know the exact difference between them.
#1. Clearing a Property Title
If the original property owner passed away without a will, the surviving family might need an affidavit of Heirship. This specific document proves legal ownership before a seller affidavit can even be drafted.
Families often use our secured RON platform to notarize affidavit of Heirship quickly to keep the real estate sale moving forward without court delays.
#2. Proving Your Primary Address
Sometimes buyers or sellers must prove their primary address for state tax purposes. You can easily complete an affidavit of Residency online alongside your closing documents. A digital affidavit of Residency is fully accepted by state tax departments and local municipalities.
#3. Handling Legal Disputes
If a real estate transaction turns into a lawsuit, lawyers use completely different forms. Process servers use an Affidavit of Service to prove they delivered court papers to the defendant. Managing multiple affidavits of service can be incredibly stressful for legal couriers on a tight deadline.
Filling out an affidavit of service form and getting it notarized online saves hours of driving. Whether you need to notarize Affidavit of Service for a local county court or a standard affidavit of service form for a federal case, remote notarization works perfectly.
