Mediator gezocht for advice about property by possible separation

Toelichting op de werkzaamheden
My boyfriend and I own a property 50% each (no papers signed that read contrary).
Currently we are not having a good situation and I am thinking on separation (not sure 100% yet).
I would like some advice about what to do with the property and how does it work. What happen if only one of the parts want to separate?
