We're both making wide assumptions, but if a person were trying to limit their liability by surrendering the AWC, i doubt they'd provide a BOS (at least for an aircraft) or builder's logs.

If it were me, trying to avoid ongoing liability, I wouldn't sell anything I'd built. I'd sell the engine, fuselage, instruments but not the wings, control surfaces, etc.

In real life, I couldn't part out my baby so I'd probably sell it whole and hope it goes well for future owners.
