I worked with another advisor previously, so I am somewhat committed to the firm, but I do like the individual I currently work with. Can I move my account when he moves?
Absolutely. While your advisor may have signed a non-compete agreement with his firm, making it a violation for him to solicit you in any manner, nothing prohibits you from voluntarily following him.
The obvious question is who is providing the value - the advisor or the firm. If it is the advisor, I suggest you inquire into what ways the new firm would add value to your family, and perhaps think through ways you may lose some value. It all depends on what services are being provided, and whether he'll be given then latitude to provide those save values at the new place. There are cases where advisors do move around a lot and other cases where firms cannot seem to keep advisors around very long. I would hope your environment is not either – but I do use that as a plus when talking with my prospective clients. Being a boutique where all the advisors are partners in the firm means stability for our clients. They know we are going anywhere, and in the unfortunate event that one decides to retire or just passes away, the remaining advisors all have the same products, processes, and business outlook. So whatever you do, I recommend you make sure you find a place you’ll be comfortable not just for today, but in the future as well.
The short answer is that yes, you usually can move your account when an advisor leaves. Your question is interesting as usually an advisor moves quickly because of the competitive nature of the business, however in this case you seem to know in advance that the advisor is leaving. Since you like the current firm, I agree with David that you would be best served to know what value the advisors new firm brings to you and your financial advisory needs. The other issue is to be sure on any costs you might incur in making a transfer to the new firm. If the advisor is moving from a brokerage firm to an RIA firm, there might be some benefits in terms of fiduciary issues but you'd have to understand the fee only versus commission based approaches. There can be significant differences. Since you know your advisor is leaving, has he/she or the current firm reached out to you regarding staying with the firm? It might be a good move to meet your new financial advisor and ask a series of questions to them about your expectations. That might clearly help you decide to stay put or to make the transition. Having made a transition about a year ago from one firm to another, I can empathize with the challenges you are looking at in terms of this decision.
Short answer: it's your money and you can do whatever you want with it.
As you feel committed to the current firm, however, my suggestion is that you give them the ability to continue to compete for your business. So, call the office, identify yourself as a client, and ask to speak with the branch manager. He or she should then attempt to match you with a suitable replacement advisor by asking you questions about your experience, expectations, views, etc.
