SOLD HOUSE BUT CONVEYANCER REFUSE TO PAY PROCEEDS DUE TO A LAW FIRM DOES LITIGATION AND CONVEYANCING ON SAME PROPERTY MATTER

the caveat is on the original contract of sale that you signed when buying the property
In many countries passing on a caveat is deemed ******* as it applies only to the first buyer but many developers try to enforce it on to the next buyer as well
Talk with your conveyancing lawyer who will be able to get a copy of the original sales contract

not a problem for fixya site
call the law society or ombudsman for the law society

Much depends on where you are, and the laws about conveyancing of property and protection of tenants.

In some places the seller must deliver vacant possession to you, or the sale is invalid.

In others tenant protection laws are so strict it is difficult to get them out even if you are a new owner.

The only thing Fixya can do is advise you to see a property lawyer.
