From the facts stated by you, your legal position is substantially stronger because: the family settlement has already crystallized rights, the compromise decree has been passed by the Court, mutation has been completed separately in each brother’s name, and your younger brother’s continued occupation is only permissive and temporary in nature.
The most important legal point is that after the compromise decree and separate mutation, the character of the property has effectively changed from undivided joint family enjoyment to separately identifiable ownership rights. Therefore, your younger brother cannot indefinitely continue possession merely by claiming status as a legal heir.
Among the three options stated by you, the most effective and legally sustainable remedy in your facts is generally:
filing an execution petition for enforcement of the compromise decree together with delivery of exclusive possession.
This is because the compromise decree already determines ownership and allotment rights between the parties. If the decree clearly identifies and allocates the specific property to you, the executing court can enforce the decree and place you into effective possession by removing unauthorized occupation or obstruction.
This remedy is usually procedurally stronger and faster than instituting an entirely fresh title suit because: title is already adjudicated, rights are already crystallized, and the younger brother cannot ordinarily reopen settled allocation issues in execution proceedings.
A fresh suit for recovery of possession may unnecessarily prolong litigation and invite avoidable procedural objections because your rights already stand recognized under a decree.
Similarly, a suit for mandatory injunction may face objections where the dispute substantially concerns recovery of possession from a person in settled occupation, particularly in a dwelling house involving family members. Courts often prefer possession-related relief through execution or proper recovery proceedings rather than pure injunction simpliciter.
Therefore, in your facts, Option B — execution proceedings seeking exclusive possession pursuant to the compromise decree — appears to be the most effective first remedy.
In the execution petition, you may seek: delivery of vacant and peaceful possession, removal/ejectment of the brother from your allotted portion, police assistance if obstruction is apprehended, and mesne profits/use and occupation charges for unauthorized continued occupation after expiry of the three-month permission.
The fact that you initially permitted him to remain temporarily actually helps establish that his possession became permissive after partition and not as a co-owner asserting hostile title.
However, before initiating execution, you should carefully examine: the exact wording of the compromise decree, whether site plans/maps are annexed, whether specific portions are clearly identifiable, and whether the decree expressly contemplates separate possession.
If the decree is vague regarding possession boundaries, the executing court may require clarification or demarcation.
You should also immediately issue a final legal notice revoking permission and recording: that the temporary indulgence has expired, his occupation is now unauthorized, and mesne profits shall be claimed.
Regarding limitation, you are presently well within time. Since the decree is of 2024 and the permissive occupation continued thereafter, no immediate limitation concern appears to arise.
In conclusion, your younger brother’s status as a legal heir no longer gives him an indefinite right to continue occupying your allotted property after partition and compromise decree. The most effective course in your circumstances would ordinarily be to proceed through execution of the compromise decree seeking exclusive possession, ejectment, and mesne profits rather than instituting a completely fresh civil suit.
