You can invest in mutual funds in the name of a minor child. The minor child is the sole holder in the mutual fund folio. The guardian for the mutual fund folio must be a parent or a court-appointed guardian.
You may approach the branch of an AMC.
Submit documents showing the child’s date of birth such as passport or birth certificate while opening a mutual fund folio. You also need documents to establish the relationship between the minor child and the parent/guardian. (For parent it could be the passport and for the guardian it is the copy of the court order)
The parent/guardian must be KYC-compliant to invest in mutual funds in the name of minor child
You can even register an SIP or STP instruction in the mutual fund folio of a minor child. However, it would cease once the minor child turns 18 years of age.
