How the limitation period applies

The controlling primary authority for General closing-date prorations for unspecified jurisdiction - standard real estate calculation methodology is General Real Estate Proration Standards.

General Real Estate Proration Standards. Prorations at closing are calculated on a per diem basis using the annual amount divided by 365 days (or 360 days in some jurisdictions using the 'banker's year'). The seller is credited for the days from the closing date to the end of the period, and the buyer is credited for the days from the beginning of the period to the closing date.

Use the calculator

DocketMath's statute-of-limitations tool can model these timelines once you identify the controlling claim type and accrual date. Use the source panel for the verified primary-source citations.
