Title subsumes ownership, but not possession that may not be germane to the sale, unless

1. the seller retains an 'interest in possession' or

2. there is a squatter, hold-over tenant or someone like a widow in possession with a registerable 'overriding' interest, namely one that can trump the sale.

Muniments include title deeds with a 'good root of title' in EN/Can law, namely docs that 1. show an unbroken chain of title 2. are at least x (15) years' old and 3. contain nothing to cast doubt on the tenure.

Also in Can & the US, deed means a conveyance of land, so IMO would be OK to use title dees here.

PS the word sold is crucial as may be a property leased.

... title deeds....

When a property is sold the notary has to verify the deeds that testify ownership.
