Short answer. No. Under Article 882 of the Civil Code, a statement of purpose in a will is a modal institution, not a condition. Your brother can claim the inheritance immediately without first proving compliance — but he must give security guaranteeing that he will carry out the testator's wishes or return what he received.
What the law says
The statement of the object of the institution, or the application of the property left by the testator, or the charge imposed by him, shall not be considered as a condition unless it appears that such was his intention. That which has been left in this manner may be claimed at once provided that the instituted heir or his heirs give security for compliance with the wishes of the testator and for the return of anything he or they may receive, together with its fruits and interests, if he or they should disregard this obligation.

Modal institution versus conditional institution
Philippine succession law distinguishes between two types of qualified inheritances. A conditional institution makes the inheritance contingent on an event: if the condition does not occur, the heir does not inherit. A modal institution does not attach the inheritance to a condition — instead, it imposes a purpose, charge, or obligation that the heir must fulfill after receiving the property. Article 882 establishes the default rule: when a will states a purpose or charge, it is presumed to be modal, not conditional, unless the testator's contrary intention clearly appears. A phrase like 'so that he may care for our elderly mother' reads as a purpose, not a prerequisite.
The heir can claim immediately — but must give security
The practical consequence of being modal rather than conditional is that the inheritance is claimable at once. Your brother does not need to wait until he has completed years of caregiving, nor does he need to demonstrate prior compliance before the court recognizes his right. Article 882 does attach one requirement to the immediate claim: he must give security guaranteeing both that he will comply with the testator's wishes and that he will return whatever he received — along with all fruits and interest — if he disregards the obligation. The security protects the estate and the mother against the risk that he inherits and then does nothing.
What happens if the obligation is ignored
The security requirement is not merely formal. If your brother inherits the land and fails to care for your mother — disregarding the modal obligation — he becomes liable to return the property together with all fruits and interests it generated during his possession. The security he posted is available to satisfy that return obligation. The other heirs or interested parties may enforce this liability if he defaults. The modal nature of the institution does not mean the obligation is optional; it means the obligation is posterior to the inheritance rather than a precondition for receiving it.
How to read the testator's actual intention
Article 882 presumes modal unless the testator's intention to make the clause conditional is clear. If the will had instead said 'provided that he cares for our mother, he shall inherit' — language expressly making the inheritance contingent — a court might find a conditional institution. But ordinary purpose language ('so that,' 'in order that,' 'for the purpose of caring for') signals a charge rather than a condition. If you believe the testator actually intended a condition — or if the security obligation is being contested — a lawyer can assist in presenting an accurate interpretation of the will to the probate court.
