The bank no doubt has language in its commitment letter stating that it can request additional documents at any time, and so on. Unfortunately, the bank will likely make an issue of your attorney's performance, in the event your deposit is lost. ...that said, if you provided all the material documentation prior to closing - and the bank is now requesting additional documents, I think you should be able to force the bank to close.
If you really want the property, your choices are to (a) file...
I would say that this is the kind of circumstance where you need to hire an attorney. If two lawyers can fight about it, if either the mother, or the legal father tries to stop you - you will probably lose if you are pro se (unrepresented by a lawyer).
It was wrong for the attorney for the company to tell you not to appear in Court, and then obtain a default judgment. While, of course, the attorney in question will deny having said something like that, if you have evidence that it was said, you have a strong basis to overturn the default.
In any event - you need to overturn the default. Judgments last for 20 years in Massachusetts, carry an interest rate of 12%, and can cause problems in your life.
Generally, you have to ask the Court's permission to amend your answer - though permission is often given. The relevant rule is Rule 15 of the Massachusetts Rules of Civil Procedure.
You can also ask the other side for permission to amend (I would do this first). They should give you permission. If they don't, then you may have to have a hearing over the issue - which would probably just waste their time, since the Court usually grants such requests.
As an unsolicited aside - if you...
Typically, you would be held responsible for the acts of your co-tenants while you were sharing the house with them. The landlord is not allowed into your apartment. So if you break the chandelier, you can say your housemate did, and how will the landlord know?
You have a remedy if you lose your deposit because of the actions of one tenant: sue that one tenant yourself in small claims court. However, it is too burdensome for your landlord for her to have to both determine the extent of the...
You don't give enough information. What are your damages? What do you want to have happen as a result of the defamation?
For example, if the defamation is ongoing, you may seek to have it stopped by the Court. You would need to go to the Superior Court to do that. I can think of three or four possible courts where you may need to file, depending upon what happened, and the relief you are seeking. So I encourage you to discuss your case with a lawyer.
Look, I do litigation, and not trusts and estates, but I think you would be crazy to use these forms from the internet. Just pay someone to do it. Shop around a little bit if price is an issue. I do not yutz with the electrical wires in my house, because I am not an electrician. Just do it right and save yourself and your family from problems down the road.
Hire a lawyer.
I have done this for clients in the past, but it is certainly an uphill battle. Moreover, you're going to need a little luck. I do offer a no fee initial consultation, but could probably figure out whether or not it made sense to discuss this with you further on the telephone.
