I have recently purchased a leasehold apartment. Inside my SPA, it stated the completion date is 90 days after the receive of confirmation letter from developer. The same lawyer is acting on both SPA and LA.

I get to know that completion date should be 3 months in the normal case, and will automatically be extended a month.

My question here is is the 3 months or 90 days period inclusive of public holidays and weekends?

What can I do if the lawyer set the completion date few weeks later than the receive date of the confirmation date?

What can I do if the lawyer trying to delay and not answering my question?
