Reference
Identify the original contract by date, parties, and contract title so the addendum plainly amends that agreement.
A Lot B Addendum lets parties record negotiated changes without redrafting the entire contract, clarifies obligations tied to a specific parcel, and creates an auditable amendment that preserves the original agreement’s intent while documenting new terms.
Common users include listing agents, buyer agents, title companies, closing attorneys, and the contracting buyer and seller who need to modify parcel-specific terms.
In many transactions the agent drafts the addendum for review but all principal parties must sign to make the amendment effective; involve title counsel if the change affects recording or chain-of-title.
Identify the original contract by date, parties, and contract title so the addendum plainly amends that agreement.
Provide the exact lot number, parcel ID, legal description or plat reference so Lot B is uniquely identified and cannot be confused with other parcels.
List changed terms (price, credits, closing date, contingencies) in numbered subparagraphs for clarity and cross-reference.
State when the addendum takes effect — upon mutual signature or a specific calendar date — to avoid timing disputes.
Provide signature blocks for buyer, seller, and their agents; include printed names, titles, and dates for each signature.
If required by state law or the parties, include a notary block or witness lines to support recordability or execution validity.
