Is It Too Late to Make an LPA If Capacity Is Borderline?

When capacity is borderline, everything comes down to one person in the room: the certificate provider. Get their judgement right, and the LPA holds. Get it wrong, and you’ve built something that can unravel the moment it’s tested.

I’m often asked this by families at the worst possible moment, usually after a diagnosis, a fall, or a hospital admission that’s made everyone realise time might be shorter than they thought. They want to know if they’ve missed the window.

Most of the time, they haven’t. But the answer depends less on the donor’s diagnosis and more on what happens in the room when they sign.

In this post:

• Why the certificate provider carries the real weight in a borderline case
• What “confident enough to sign” actually looks like in practice
• What happens when a certificate provider pauses instead of signing
• When it’s worth bringing in an independent capacity assessment before the appointment goes ahead

The Certificate Provider Is the Person Who Actually Decides

Every Lasting Power of Attorney needs a certificate provider. This is someone independent of the attorneys being appointed, who confirms at the point of signing that the donor understands what they’re doing and isn’t being pressured into it.

It sounds like a formality. It isn’t. In a borderline case, the certificate provider’s judgement is the thing standing between a valid LPA and one that can be challenged years later.

I’ve worked alongside solicitors, GPs, and lay certificate providers over the years, and the good ones share one trait: they’re willing to slow down. They ask proper questions. They watch for hesitation, confusion, or a family member doing too much of the talking. They don’t sign just because the paperwork is ready and everyone’s keen to get it done.

What “Confident Enough to Sign” Actually Means

A certificate provider doesn’t need to be certain in a clinical sense. They’re not carrying out a formal capacity assessment. What they need is a genuine, honest belief that the donor understands the decision in front of them.

In my experience, that usually shows up in small, observable ways. The donor can explain, in their own words, roughly what they’re agreeing to. They can say who they’re appointing and why. They respond consistently across the conversation rather than agreeing with whoever spoke last.

None of that requires sharp memory or quick thinking. I’ve sat with people who couldn’t tell me what day it was, but who understood perfectly well that they were giving their daughter the authority to manage their bank account if they became unwell. That’s the test. Not general sharpness, just understanding of this specific decision.

Where a certificate provider can honestly say they’ve seen that understanding, the LPA can proceed. Where they can’t, that’s the moment to stop.

When the LPA Certificate Provider Pauses

This is the part families sometimes find hardest to hear: a good certificate provider will sometimes say no, or at least not yet.

I’ve seen appointments paused because the donor kept deferring to a relative in the room rather than answering for themselves. I’ve seen them paused because the donor’s answers changed significantly between the start of the meeting and the end. Neither of those means the person definitely lacks capacity. It means the certificate provider isn’t yet confident enough to put their name to it.

That pause can feel frustrating, especially when a family has been building up to this appointment for weeks. But a certificate provider who signs under pressure to “just get it sorted” isn’t doing the family any favours. An LPA signed on shaky ground is far more vulnerable to challenge later, often after the donor has died and there’s no way to ask them what they understood at the time.

A short delay now is almost always easier to live with than a legal challenge in three years’ time.

When It’s Worth Bringing in an Independent Assessment

Most LPAs don’t need a formal capacity assessment. A careful certificate provider, given time and the right conditions, is usually enough.

But there are situations where I’d recommend arranging one before the signing appointment even happens, rather than waiting to see how it goes on the day. These include cases where capacity is known to fluctuate significantly, where a family member disagrees with the decision, where there’s any suggestion of undue influence from someone who stands to benefit, or where the estate is large or complicated enough that a future challenge is a real possibility.

As an independent social worker, I’m not attached to the Local Authority and I’m not appointed by any of the family members involved. My only job is to sit with the donor, in their own home if that suits them best, and form an honest, evidence-based view of their understanding. I write that up clearly, so the certificate provider, the solicitor, and the family all have something solid to work from.

That report doesn’t decide the outcome for anyone. It gives the certificate provider the confidence to proceed, or it makes clear that a deputyship through the Court of Protection is now the safer route.

What This Means for Your Family

If you’re arranging an LPA for a loved one and you’re not sure how the appointment will go, the honest answer is: nobody can promise you in advance. What you can do is choose a certificate provider who’ll take the time to look properly, rather than one who’ll rush through it.

If there’s any doubt at all, raising it before the appointment, not during it, gives everyone a much smoother path forward.
