Short answer. Yes, as a starting point. Article 446 of the Civil Code presumes that all works, sowing and planting were made by the owner of the land and at his expense. It is a presumption of fact, and anyone who says otherwise must prove it.
What the law says
All works, sowing, and planting are presumed made by the owner and at his expense, unless the contrary is proved.

What the presumption gives the landowner
The rule saves the owner from having to prove the obvious. A house, a fence, a fishpond, a stand of fruit trees or a season's crop sitting on titled land is treated, without more, as the owner's work and paid for out of his pocket. He need not produce receipts for cement bought thirty years ago or name the carpenters who did the job. The practical effect is procedural: the burden of proof shifts. Whoever claims to have built or planted it must come forward with evidence. That is a real advantage in the ordinary case where an occupant asserts, years later, that the improvements were his.
It is rebuttable, and often rebutted
The article ends with the words unless the contrary is proved. Contractors' agreements, building permits in another name, receipts for materials, payroll records, photographs taken during construction, tax declarations covering the improvement separately from the land, and the testimony of workers or neighbours all defeat it. Because the presumption is only a starting position, a landowner who relies on it alone in a genuinely contested case is relying on very little. Where the improvement was recent and someone else claims it, the sensible course is to build the documentary record now rather than lean on the article and hope the other side has nothing.
What follows once someone else proves he built it
The presumption decides who is taken to have built, not what happens next. Once it is shown that another person did the work, the Civil Code's rules on accession take over, and they turn heavily on good faith. A builder, planter or sower in good faith is not simply stripped of what he spent; the landowner is generally put to a choice, and indemnity or removal comes into play. A builder in bad faith is treated far less generously. So proving that the neighbour built the extension is only the first step in his case, and it does not by itself hand him any part of the land.
Where these disputes actually arise
Three situations recur. A family member allowed to stay on the property builds a house and later claims it. A buyer takes land and finds an occupant asserting years of improvements. And co-heirs argue over who paid for what before partition. In each, the presumption favours the registered owner, but the arithmetic of reimbursement can still be substantial. Keep receipts, permits and dated photographs for anything you build, whether on your own land or on someone else's — they are what decides these cases. No outcome can be promised. Take advice before demolishing anything or accepting a payment, because doing so can concede more than you intend.
