Your goals, our mission

Be there.
Be dad.

We are the wind at your back and the sun on your faces, so that every parent can reach for the stars with their child.

  1. 100% of the cash support is paid by the parent who sees the kids only every other weekend.

    Time with your kids counts – in euros too. From the first day beyond the "usual contact rights".

    More dad. Not just a payer.

  2. Information on the highest possible cash support as a moral obligation. Everywhere.

    Every duty comes with rights. We show you which rights you have.

    An ethically correct amount. Enforceable.

  3. The recipient owes no account of how the money is spent. The payer may watch. Changing anything: forbidden.

    We calculate the child support of the future. For you. For your kids.

    For your rights. Your future.

  4. Often 'all eyes on you'. What was fine yesterday is dangerous today. Blame-based. A financial one-way street.

    Our calculator and our tips strengthen your position. Legally, tax-wise and personally.

    Stronger together. Than ever.

General information, as of 2026. Tax example: two children under 18, support paid in full, enough wage tax. A calculation aid, not legal advice.
