What is the ruling on marriage by reciting Al-Fatihah without the guardian's consent for a divorced woman in a foreign country to a man legally married to a foreign woman, who is unable to marry again?

A valid Islamic marriage has conditions and pillars without which it is not sound. These include the guardian (wali) and witnesses. The marriage of a woman without a guardian is invalid according to the majority of scholars. Documenting the marriage is not a condition for its validity, but it is necessary in this era to prevent corruption and the loss of rights.
