Short answer. No. Acts merely tolerated do not affect your possession, so however long a relative stays by your permission, the years do not build into a claim against you. The risk is not the law — it is proving afterwards that what happened was tolerance rather than something else.
What the law says
Acts merely tolerated, and those executed clandestinely and without the knowledge of the possessor of a thing, or by violence, do not affect possession.

Three kinds of acts that count for nothing
The article sweeps together three situations and gives them the same treatment: acts merely tolerated, acts done clandestinely and without the knowledge of the possessor, and acts done by violence. None of them affect possession. What unites them is that the possessor never genuinely yielded — he permitted, or he did not know, or he was overborne. Time spent on the land under any of these conditions does not accumulate into anything, however many years of it there are and however settled the arrangement looks from outside.
Why permission is the opposite of a claim
A claim to possession has to be adverse — held against the owner rather than under him. Permission removes exactly that quality. The relative living in the back house is there because you allow it, and every day of his stay is an acknowledgement that the land is yours to allow. This is why the generous arrangement is safe in principle and why the article can be so short. It is also why nothing changes when the arrangement passes to the next generation: a son occupying by the same tolerance is in the same position his father was.
Where these arrangements actually go wrong
The danger is evidentiary, not legal. Tolerance is usually spoken and never written, so a decade later the two sides describe the same facts differently — the owner remembers letting a cousin stay, and the cousin remembers being given the lot. If the occupant paid for anything, contributed to a building, or handed over money that could be called rent, the character of the stay is genuinely in play. Silence for twenty years is not a legal problem, but it is a proof problem, and it is the one that fills the courts.
Fixing it while everyone is still friendly
Put the tolerance in writing, even in a paragraph: who owns the land, who may stay, on what terms, and that the permission may be withdrawn. If money changes hands, decide honestly whether you have a lease rather than an accommodation, and document that instead. When you want the land back, the sequence begins with a demand to vacate, dated and received — that is the moment tolerance ends and the occupant's continued stay becomes something a court can act on.
