Capital Gain Tax on individual sale/joint purchase

Query: capital gain.
Property sold by wife was in individual name. (It was bought in 2001 & sold in 2023).

Another property purchased in joint name of husband & wife.
Full amount reinvested but in joint name.

Question is:
While calculating capital gain of wife, full amount of new property will be considered as reinvestment or only half? - as new property bought is in joint name of husband & wife.
