Absolutely. It's a very common experience and it's called litigation harassment. There is a lawyer on the other side, or potentially an abuser on the other side, who just runs out the resources. They bring all kinds of applications, everything they can think of to throw at the wall and see if they can exhaust the resources so that the person will walk away from whatever rights they have. One of the things you can exhaust is the financial resources, but you can also exhaust the legal aid hours.
So yes, it's a very common problem.
