as per general Rent control act, you have every right to ask the tenet to vacat the house with reasonable notice ,irrespective weather you have the written agreement or not.

you have several options..

1. Speak to your elder and ask them to vacate the house and they don’t ( Sort out of court )

2. give a complaint in local police station on 2 things.. under Private nusience, and also on not vacating…

if police takes it , they can simple ask them to vacat and the issure resloves..
