Advocaat/Jurist gezocht: ik moet mijn huis uit omdat ik illegaal zou huren van de hoofdbewoner

Toelichting op de werkzaamheden:

I trust this message finds you well. I am currently looking for a lawyer that is specialized in huur recht. I am living in an apartment together with the hoofdbewoner. I am not in the contract but I have lived here for 13 years together with the hoofdbewoner. There has been a recent address/house investigation in which the woningbouw is stating that the hoofdbewoner is not living here and has given the apartment to me therefore they have sent him letters to cancel the rental agreement which of course he will not to do as he lives here. I have also received a letter yesterday to move out by Friday as they are stating that the hoofdbewoner doesnt live here and has given the apartment to a third party in this case me. I am registered on this address at the municipality since day one. I therefore would like to know my rights and kindly looking for a jurist to defend me.
