The deal & money

BAST (handover act)

BAST (акт приёма-передачи) · Berita Acara Serah Terima

In one sentence. The document by which the villa is handed to the owner after the final inspection. It starts the warranty periods and triggers the last 10% and the launch of rental.

BAST (Berita Acara Serah Terima) is the bilateral handover act. It comes with a snag list with deadlines for fixes, the as-built fit-out specification, keys and access codes, and the document set (PBG, SLF, utility drawings, equipment manuals).

In DOMA projects the BAST is signed after the SLF is obtained, and the final 10% is paid on signing. Contractor warranties run from that date, 5 years for structure, 2 years for utilities, 1 year for finishes and equipment. With the keys the investor receives the villa's digital passport, and the owner portal switches to operating mode.

Do not sign the BAST without an on-site inspection, yours or an independent engineer's. After signing, visible defects move from "outstanding works" to "warranty claims", a different procedure with different timelines. The inspection checklist is in the article.
