<human>: Hi guys,

My parents have been divorced for a couple of years and the house has been up for sale for almost as long (we live in the Netherlands). All bids have been massively under our mutually agreed "bidding starts at" price and have thus been rejected by my mom.

My dad doesn't care that his kids live in said house and would rather see it sold today than tomorrow, for dirt cheap if it must. Now today my mom received an email from my dad's lawyer stating that she has 2 days to sign the contract, or there will be legal action. 

Is this even allowed? My dad is a 'jurist' which is something like a legal expert, so he knows his way around the law. My mom is not the type of person to fight back and I fear my dad will waltz right over us if we don't do something.

Give me a shortened version of the text
<bot>: 'Lawyer' dad wants to take my legal-layman mom to court. Is there anything we can do, given this short time frame? And if not, how could we best prepare ourselves?
