Long story short, DP and I are marrying this year, we want him to have parental responsibility for my DCs. He is their parent in every way apart from biologically, their actual dad shows no interest in them whatsoever (there's a long post on AIBU if you want the full story). However actual dad is refusing to allow PR for DP. Anyone had any experience of applying through the courts to allow a step parent PR without NRP consent? I'm fairly certain they'd grant it based on the circumstances, but I don't even know where to begin!
