I have evicted multiple times in VA, most recently in Henrico - you really don't need a lawyer.Read this: https://ipropertymanagement.com/laws/virginia-eviction-proce...The clerk of court is usually helpful, they can't provide legal advice but they can answer questions about the forms.Also, sit in on some court hearings for evictions (unlawful detainer), they usually have specific days scheduled for these hearings - the courts are open to the public.

In Virginia I would submit a suit for unlawful detainer to get a judgement against both the parents and the child (essentially an eviction).

I own the property and they are unlawfully occupying it, Yes ?   

That moves you for paying to relocate them, to paying for the downpayment on their new house and car when they sue you and win.if your state permits, file your unlawful detainer, and then negotiate the cash for keys where upon leaving you will dismiss the suit.

Can this be a problem when I fill UD-100 (unlawful detainer), as 6 d and 6 e mentions rent changes, addendums?

Gives me more people to name in an unlawful detainer filing if rent lapses.

If the tenant does not move out after 60 days, then you will have to file an unlawful detainer case. 

You will probably want to file an unlawful detainer which is not hard to do yourself and then show up to court.
