Joint development agreement when minor intrest involved

For alienation of an immovable property involving minor interest, court permission is pertinent.

Since your daughter is likely to become major by next year, you may plan to defer the development program until then because by the time the court would decide to grant you permission to alienate the property involving your minor daughter's share, she will become major by age.

Yes.  Please wait till your daughter gets the majority of age.  If now, you have to get court permission for your minor daughter's share.
