No co-owner shall be obliged to remain in the co-ownership. Each co-owner may demand at any time the partition of the thing owned in common, insofar as his share is concerned.
Nevertheless, an agreement to keep the thing undivided for a certain period of time, not exceeding ten years, shall be valid. This term may be extended by a new agreement.
A donor or testator may prohibit partition for a period which shall not exceed twenty years.
Neither shall there be any partition when it is prohibited by law.
No prescription shall run in favor of a co-owner or co-heir against his co-owners or co-heirs so long as he expressly or impliedly recognizes the co-ownership. (400a)
