Lawyers recommendation

Can anyone refer me names and contact info of three different lawyers practicing real estate n karachi area.

Anis sahab lawyers in Pakistan rarely specialise in real estate law per se. Generally, Lawyers who practice transactional law can assist you with real estate deals and lawyers who practice litigation can assist you on real estate disputes.
So any recommendation with regard to lawyers will depend on what is it that you need assistance with.
If it is an issue dealing with agricultural land, then it will be best to get a lawyer who understands land revenue, tehseeldar and patwari system.
