What happens to my brother for breaking his lease on an apartment?
Your brother has agreed to the terms of the lease. If it is a large apartment complex they are more likely to hold him to it than an individual owner. They can require that he pays the rent for the entire 8 months remaining. They are within their rights and it just depends if he has enough assets for them to pursue a court case against him. If he had any co-signers, they will also be responsible. They could also garner his wages if that is the only way to get their money. The best course of action would be to find someone else to sub-let to and ask the landlord to substitute their payments for the remaining term of the lease.
