Who does what in a Long Island home sale

A Nassau or Suffolk sale usually has more than two people in the file. The New York State Unified Court System describes home purchases as attorney-led on the contract and closing. This page names the common roles so a seller can see who typically owns each step. It is a process map, not an assignment of legal duties.

The seller

The seller decides to list, confirms the property file, and reviews proposals. The seller also supplies documents the later contract and closing will need: tax-lot identity, permit history, and any known municipal or village records. A Long Island mailing address does not by itself set those records.

The buyer

The buyer makes a proposal, arranges financing if they need it, and works with their own attorney. Inspection and insurance choices belong to the buyer and the people they hire.

Each party’s attorney

Each attorney advises only their own client. In many Long Island sales the seller’s attorney prepares or reviews the proposed contract, and the buyer’s attorney reviews it before signing. Attorneys also handle closing documents. They do not share one “house attorney.”

Title and closing professionals

Title, recording, and related closing work are done by the companies the parties engage for that sale. Those companies confirm the lot, liens, and recording path. Their fees and documents are specific to the transaction.

What Rellia’s file is for

Rellia is the shared software file for a listing that runs on the platform: tasks, documents, and a path from estimator to listing. Sellers can start from the estimator or from a town page. Rellia does not inspect the house, write the contract, lend money, or record the deed. Those steps stay with the people named above.

For the order of steps, see the New York sale timeline guide. For how the contract draft usually moves between attorneys, see the attorney-review guide.
