Thanks in part to the highest unemployment rate for college graduates in 11 years, more students are deferring repayment of student loans and leaving school with more debt than ever before.

Even though more than half of college graduates under age 25 are unemployed or underemployed, there are other reasons to why a TransUnion study found that more than half of student loan accounts are in deferred status: The large loan amounts don't register with them, says Tom Yarnell, director of financial aid at Otterbein University in Westerville, Ohio.

"I don't think they realize how long it takes to pay it back and the amount they'll have to pay back," Yarnell says.

"Students at that age level have their eyes on something other than the borrowing amount and are pretty sure they'll be able to get a job and pay the loan back," he says.

 The loan amounts can be overwhelming. Student loan balances increased 75% between 2007 and 2012, with the average debt per borrower increasing by 30% to $23,829, according to the TransUnion study.

But there is some good news for students -- for those who have federal student loans, anyway. The loan interest rates on those loans are lower than private loan interest rates because they are subsidized by the federal government, and borrowers have more legal rights with federal loans than they do with private loans. Here are nine rights students have for federal loans:

1. The right to loan counseling. Federal laws require loan providers to spell out the terms of loans to borrowers, but student loans are unique because they require borrowers to complete entrance and exit counseling before and after they get a loan so that they understand the terms, says Helen Nunn, director of financial aid at Susquehanna University in Selinsgrove, Pa. The National Student Loan Data System provides online counseling to help understand loan terms and rights and responsibilities of repayment.

"Once they get that far into the funnel, that they're actually signing up and receiving loan funds, there's quite a bit of information and counseling they have to do," Nunn says.

2. Right to contact your loan servicer. This right applies to all types of loans; you can contact your loan provider any time you want. But with student loans, the servicers that are contracted by the Department of Education to coordinate billing make it easy to contact them to answer questions, Nunn says. They also provide a lot of information that students may not even read, but will help them, says Greg Gearhart, director of financial aid at Messiah College in Grantham, Pa.

"There are lots of rights and responsibilities that students have with their loans, but they get all of that information as part of their Master Promissory Note and the loan entrance and exit counseling processes," Gearhart says.

"The loan servicer sends them all kinds of disclosures," he says. "On that basis, you could say that they already know everything they need to know, but it is true that we constantly joke about how students don't need anything we send them and I'm sure any given student you ask might not know of something she should."

3. Right to defer payment. If you're in graduate school or the military, loan payments can be deferred until you're out. A hardship deferment can also be given to the unemployed, or forbearance if a borrower is sick and unable to work. A forbearance allows monthly payments to be discontinued or shrunk for up to 12 months. Interest will still accrue during the time off from the loan.
