Short answer. By judicial partition. The Code gives two routes only — agreement between the parties, or court proceedings — so when agreement fails, one co-owner files and the court supervises the division. No co-owner can block it indefinitely by simply refusing to sign.
What the law says
Partition may be made by agreement between the parties or by judicial proceedings. Partition shall be governed by the Rules of Court insofar as they are consistent with this Code.

Two routes, and only two
Article 496 provides that partition may be made by agreement between the parties or by judicial proceedings. There is no third path, which is worth saying plainly because families spend years looking for one. A co-owner cannot divide the property by taking possession of a portion and fencing it, nor by having a survey made and treating the resulting plan as binding, nor by selling what he calls his part. Until a partition exists in one of the two recognised forms, every co-owner still holds an undivided share in the whole and the arrangement on the ground has no legal effect.
Why agreement is worth exhausting first
An agreed partition is faster, cheaper and drawn by the people who know the property. It lets the family trade what actually matters — the house to whoever lives in it, the roadside frontage to whoever will build, cash to whoever wants out — in a way a court dividing by proportion cannot. The requirement is that everyone with a share signs, including heirs who have never seen the land and relatives abroad. That is usually the sticking point, and it is worth solving with a special power of attorney rather than by leaving somebody out, since a partition missing a co-owner is not binding on him.
What happens when it goes to court
The proceeding first settles who the co-owners are and what each one's share is; only then does it turn to dividing the thing. If the property can be split into usable parts, it is split, with adjustments in money where the parcels are not of equal value. If it cannot be divided without making it unserviceable, the court does not force a division — the property is assigned to a co-owner who pays the others, or sold with the proceeds distributed by share. The accounting between the co-owners for rents, taxes and expenses is settled in the same proceeding.
What to have ready before filing
The certificate of title and the latest tax declaration; the documents that establish how each person came to have a share — the death certificate and any will or settlement where the property was inherited, deeds where shares were bought or sold; and a current list of every co-owner with their whereabouts, since all of them have to be brought in. Add a survey and, if the property is likely to be assigned or sold rather than split, an appraisal. Most delay in these cases comes from missing heirs and missing documents rather than from anything the court does.
