Avengers actor Jeremy Renner is once again in conflict with his ex-wife Sonni, the mother of his 6-year-old daughter. The Canadian model now requires full custody of the girl, TMZ reports based on legal documents.

Why Sonni wants to have the previously agreed shared guardianship adjusted is not clear. The exes have been arguing for years in court and beyond. For example, the model previously claimed that the actor’s weapon collection was far too easily accessible for their daughter and that this put her at risk, which Jeremy again denied. They also disagreed about the amount of alimony.

The 48-year-old actor, best known as Hawkeye in various Marvel films, married Sonni in January 2014. The two split up ten months later.
