Addendum to Purchase Agreement (Universal) — Louisiana Edition Template

Deals change after signing — repair credits get negotiated after inspection, closing dates slip, appraisal gaps get bridged, personal property gets added or removed. The clean, enforceable way to document any of it is a written addendum executed by all parties, because nearly every purchase agreement contains an integration/merger clause providing that modifications must be in writing, and the statute of frauds in every state requires material modifications to real estate contracts to be written anyway.

This Universal Addendum to Purchase Agreement is deliberately flexible: it identifies the underlying contract by parties, property, and effective date; provides numbered blank provisions for the new or modified terms; states that all other terms of the purchase agreement remain in full force and effect; handles conflicts between the addendum and the original agreement (addendum controls); and includes execution blocks for all buyers and sellers with dates. It is the form you reach for dozens of times a year.

The 3-page template also ships with a drafting guide containing ready-to-adapt clause language for the most common addendum scenarios: inspection repair resolutions, closing date extensions, appraisal gap provisions, seller concessions and credits (with a note on lender concession caps), personal property inclusions, post-closing occupancy stubs, and contingency waivers. The 50-state notes flag jurisdictions with specific counterpart-execution or electronic signature nuances (all states have adopted UETA or equivalent, and federal E-SIGN, 15 U.S.C. § 7001, validates electronic signatures, but practice details vary). Template for drafting purposes — review significant modifications with a broker or attorney.

About this Louisiana Edition: Louisiana is the only civil-law jurisdiction in the library, and every template was redrafted in its vocabulary — immovable property, parishes, the act of sale, and the Louisiana Civil Code rather than common-law contract doctrine. Agency terms follow the Louisiana real estate agency disclosure statutes (La. R.S. 9:3891 et seq.), which require the Commission's agency disclosure pamphlet and permit dual agency only with written informed consent from both the buyer and the seller, so the dual agency consent here is a true consent instrument. The seller disclosure edition is built around the Louisiana Residential Property Disclosure Act (La. R.S. 9:3196 et seq.) and the Commission's mandated property disclosure document, the listing and buyer agreements carry the written-agreement and definite-term requirements enforced by the Louisiana Real Estate Commission, the independent-contractor agreement reflects sponsoring-broker supervision under the Louisiana Real Estate License Law, and each instrument recites the Louisiana Uniform Electronic Transactions Act and the civil-law writing requirement for transfers of immovable property.
