There's absolutely no such need for a service for such a simple problem. How can you trust a centralized entity to give your Bitcoins to your family upon death, when you can't trust your family with your wallet?
It's completely useless, just ensure that they have access to your private keys.

This. Im not sure if I will have kids yet so that's not a problem so far. As far as my family goes, I think it's all our case the fact that none of our family members has any idea of what bitcoin is, let alone how in hell enter your password in your bitcoin core node and take control of the keys (and most importantly, kept them safe). Telling someone else to do it for you is a recipe for getting your BTC stolen from your family.

Honestly, I don't even want to think about it. Im still young and I hope I can retire with my BTC, im not thinking about inheritance but how to make more BTC.

Hey
No one in my family knows about my private key and everything else, bitcoins is something that they know about for sure.
Inheritance service in Bitcoin world is something that will for sure be officially given a place and accepted if bitcoins continue to flourish, also even now non officially you can give the key to your family members and friends and no one will ever ask you if you wrote about bitcoins its key and wallet in your last will, because you can write anything you want the others to have... Bitcoins are no big deal so even now if you want to you can do that too.

That's something to think about in the future when Bitcoin gets into the mainstream. At the present it seems like there will be no takers for such a service.

I do not think the need for inheritance services, all we need is how we can educate children when they learn enough to reveal our personal secrets as we go, and our children can open access our secret wallets and take what we left behind. So the child can feel the result of the bitcoin we leave behind

Even I am of the opinion that we don't need any such service. In my personal case my wife knows all about bitcoin and if or when any such situation as mentioned in the op occurs my wife knows it all what to do and how to access the bitcoins I hold in my wallet. But yes other members may have different case but still I don't think any of them would allow third party intervention and would let them play with their bitcoins.

Why do you need such a service anyway? Do you not trust your family with your bitcoin? I know they might not know about it, but you can do them a favor and right your will attempting to explain what bitcoin is all about. Plus, I am sure that there is someone whom you can trust. Let is say you do not trust any of your family. Let is also say they can get greedy. But I think that there is another member whom you can share your stories with. I mean if you do not trust your family, then who are you going to trust? Despite the problems I am facing with my family members, I always see the positive side. I trust my mom to the fullest. So I think you should give your wallet to your mom.

But this is a different space. Do lawyer even know how to deal with bitcoin private keys? how do you know you can trust them? Has this ever been done before?

I would need to see how this actually went down in a real case, I just can't trust people including lawyers.

I discussed this with my partner recently.. He's not very familiar with crypto wallets but I've created some instructions for him, should something happen to me. He knows where my wallets/drives are and kinda knows the information he'll need to get at my coins.. I'm sure he'll be able to work it out with the info I have given him.

That's all I have as a plan for now but I'm only 37 and have just under $100k in crypto. Over the next year or so as my wallets increase, I'd like to have a better plan than that.

I was recently looking into a service in Australia (where I live) that can insure your Bitcoins, trading accounts and provide a service similar to what you are talking about but I'm not sure about it: https://bitcointrader.org.au/

I'd love to hear from anyone in Australia who has used this service, what are your thoughts? Good/bad experience?

I agree. A lawyer is a single point of failure.  With a decentralized solution that deposited the funds to an account after x number of days of  inactivity by the person who signed up for this decentralized service there would be no need to trust a 3rd party (lawyer)
