10 Day Notice To Cure

[Skier]

If a 10 Day Notice to Cure is "cured" by said date and the tenant puts it in writing, has it legalized by an attorney and deliverd to LL, does this eliminate the possibility that LL can start terminating procedures through the court?

The reason I ask is because the tenant has decided to cure the notice by terminating his rights to the lease instead of going through the points one by one.

If all is said and done, is there likelihood that the LL would try to sue tenant later on for remaining "unused" months on lease or is this just far too much trouble and more time consuming than it is worth?

Thanks
