After a divorce there are many doubts and pending accounts. The payment of community expenses is part of that concern that comes after a separation. If the apartment belongs to both spouses, since there is a pro undivided property, the community can direct the receipt against the spouse who remains using the home.
However, the community is not obliged to do so, in such a way that it will continue to send the communications to the address, unless the property is the exclusive property of the spouse who is not awarded the use of the property. For the community of owners, the separation is irrelevant in cases of gains from the flat.
If it is exclusive to those who do not use it, it will be the person who must transfer their new address to the community, although the person responsible for paying the expenses will continue to be the owner, not the one who uses the property. The community must therefore claim payment from the owner as well as claims for non-payment or delay.
