Office Lease

Can someone please tell me a website or how to write a letter to end lease office space we rent from? I'm just looking for a model. We are not leaving on bad terms it only states in our contract that we need to let them know that we will not renew 90 days in the market being '. I wish she looks like a legal form (as a lawyer wrote). Thank you!

He does not need to be something special.

Just "under the terms of the lease that we provide notice beyond that required 90 days we will not renew the lease expires XX / XX / XX."

Include something "We really appreciate doing business with you." Just to look pretty Nice Incase you need a reference.

"This letter is our view that we intend to leave on date X, pursuant to Article X (about any point and termination) of the lease dated X". This should be sufficient .
