Help, any opinions, advice or suggestions!?

My sister rents a townhouse in Baltimore County, MD. She and her friend signed a year lease. The friend, over the last five months, has insisted they don't have their share of the rent. My sister has talked, begged and pleaded with this individual to come up with their share of the rent to no avail and she has exhausted her savings to pay all the rent. The rental office has told her one more late payment with the rent and she will be evicted. She and the co-tenant have another two months on the lease. My sister has explained the situation to the rental office but they said there's nothing they can do. If the roommate has signed the lease too isn't there anything legally my sister can do?

If both your sister and her friend signed the lease, they are both responsible for the rent. However, from the management's point of view, how the rent is split up between the two of them isn't their problem. The rent is due no matter who pays it.

Because they are both on the lease, they are both going to be evicted for non-payment of rent. Unless she can continue to pay the rent for the next two months and then move out, she and her roommate are both going to be held equally responsible for the eviction, and both will be sent to collections and have a black mark on their credit reports.

The only other thing she can do is convince the roommate to move out now, and find someone else to move in. Make sure she does this legally through the apartment community office, though, and forms are signed that officially remove the roommate from the lease, otherwise it won't have any bearing at all.

take the other party to small claims court to try and recoupe her share of the rent.

Your sister needs to evict her friend before the landlord evicts both of them. Obtaining a Peace Order is only good for 6 months but I doubt that non-payment of rent is grounds for obtaining such an order.

Your sister could also find another roommate who can take over the rent but that would require ejecting the friend who doesn't pay. Maybe your sister needs to throw her friend's belongings on the street - that person will get the hint.
