Lease is expiring

Well, you'll want to look for a notice provision in your current lease.  If the current lease dictates that you must give 60 days notice, then you may have to deal with a breach of that provision. However, if that provision is not in the lease, you will likely have no problem should you choose to move out.  That said, make sure your landlord has your new address so he or she can either return the security deposit or provide notice of an intent to claim against it for damages above wear and tear.  If you are unsure of your rights and obligations under your lease, it would likely be to your advantage to have it reviewed by an attorney.  Even if there is a 60 day provision in your lease, if you are aware, you may still be able to work out an amicable solution with your landlord.  An attorney can better explain your options after reviewing the lease and any communications you've had with the landlord.
