Wisconsin Guardian ad Litem: Role, Cost, and What to Expect in an Elderly Guardianship

The moment you file a guardianship petition in a Wisconsin circuit court, the judge appoints a guardian ad litem. This is not optional — it happens in every single case. Understanding what the GAL does and how to work with them can mean the difference between a smooth hearing and a months-long contested proceeding.

What a Guardian ad Litem Does

A guardian ad litem (GAL) is an independent attorney appointed by the court to represent the best interests of the proposed ward — your aging parent. The GAL is not your parent's lawyer in the traditional sense, and they don't take direction from you. Their job is to investigate the situation and tell the court what outcome would best serve your parent.

Under Wisconsin's guardianship statute (Wis. Stat. ch. 54), the GAL must:

• Physically meet with your parent — not just review paperwork
• Explain your parent's legal rights to them orally, including the right to a jury trial, the right to be present at the hearing, and the right to their own defense attorney
• Investigate the proposed guardian's suitability — the GAL will ask about your relationship with your parent, your financial situation, whether siblings agree, and your plan for managing your parent's care
• Submit a written report (Form GN-3160) to the court with their findings and recommendation

GAL vs. Adversary Counsel

These two roles get confused constantly. The GAL represents your parent's best interests as the GAL sees them. Adversary counsel represents your parent's stated wishes — what the parent actually wants, even if the GAL disagrees.

If your parent or the GAL requests it, or if anyone contests the guardianship, the court must appoint adversary counsel separately. This means your parent could have two attorneys: the GAL arguing that guardianship is in their best interest, and adversary counsel arguing that your parent doesn't want it.

What the GAL Investigation Looks Like

Expect the GAL to:

• Visit your parent wherever they're living — hospital, home, or care facility
• Interview you and any other proposed guardians
• Talk to other family members, especially if there's disagreement about who should be guardian
• Review your parent's medical records and the physician's evaluation (Form GN-3130)
• Check whether less restrictive alternatives (like a power of attorney or supported decision-making agreement) might work instead

The investigation typically takes two to four weeks, depending on the complexity of the case and the GAL's caseload.

What a GAL Costs

The court sets the GAL's fees, which are paid from the proposed ward's estate — your parent's assets. Rates vary by county, but typical GAL fees in Wisconsin guardianship cases range from $500 to $2,000 for uncontested cases. If the case is contested — a sibling objects, or your parent refuses the guardianship — fees can climb to $3,000 or more as the GAL's investigation and hearing time increase.

The GAL fee is separate from the filing fee, the physician's evaluation fee, and any attorney fees for the petitioner or adversary counsel. These costs add up quickly, which is one reason why executing a power of attorney while your parent still has capacity is so much more cost-effective.

How to Prepare for the GAL Visit

You can't control the GAL's recommendation, but you can make their job easier:

1. Have your parent's medical documentation organized — diagnosis, medications, recent hospitalizations, cognitive test results
2. Be ready to explain why guardianship is necessary — specific examples of your parent's inability to manage finances or make safe decisions
3. Document that you've considered less restrictive options — if a POA wasn't possible because your parent already lost capacity, say so clearly
4. Resolve family disagreements before filing if possible — contested guardianships cost more and take longer for everyone, including your parent
