It is a Tuesday afternoon at a law firm, and a partner who owns shares in several public companies wonders whether glancing at a brokerage app between client calls is a problem. The short answer is that investing for yourself and billing clients are separate activities, and the way to keep them separate is to keep them on separate clocks, inside the limits of your firm's policies and the rules of your jurisdiction. Nothing here is legal advice, and your own firm's policies govern. The questions below cover the practical separation most partners need to think through.

Key Takeaways

  • Personal investing and billable work should run on separate, clearly delineated clocks.
  • Your firm's written policies and your professional rules come first, and they vary.
  • Scheduled personal time for portfolio matters is easier to defend than checking in whenever you can.
  • Questions about conflicts, restricted securities or timing belong with your firm's compliance contact.

What does it mean to separate trading time from billable hours?

Billable hours are time you record because a client is paying for it. Personal investment activity is time spent on your own affairs. Separating them means that time you spend on one is never recorded or treated as the other, and that attention paid to your portfolio does not erode the time and focus clients are entitled to.

In practice there are two separations. The first is a bookkeeping one: personal time is not recorded as client time, and client matters do not run into time you meant to give to your own affairs. The second is a behavioral one: you decide when you will think about your holdings, so that checking prices does not creep into work blocks.

Most partners find the behavioral separation harder. A phone lets you look at a quote in seconds, and those seconds can accumulate. A rule such as "portfolio matters only in these scheduled windows" is simple, and it makes the line easy to explain if anyone ever asks.

What do firm policies and professional rules usually require?

This depends on your firm, your role and your jurisdiction, so the first step is to read your firm's written policies. Many firms have rules about personal securities trading, particularly where the firm represents public companies. Common features include restrictions on trading in securities of certain clients, requirements to disclose or pre-clear some transactions, and periodic reporting of holdings.

Professional conduct rules also apply, including duties around confidential information. Information you learn through client work is generally not something you may use for personal investment decisions. Because the specifics differ, your firm's general counsel, ethics partner or compliance office is the right place for questions about what is allowed.

If you are unsure whether a particular security or transaction is covered, ask before you act, and keep the answer in writing. A short email asking for guidance is inexpensive compared with the cost of a misunderstanding.

How can I schedule personal investing time in a demanding week?

Treat portfolio time as an appointment that you place outside the working day, such as early morning, a weekend slot or a protected lunch hour that you do not bill. Choose a recurring window and keep it short. For a portfolio of long-term holdings, thirty minutes a week is often enough for review, with a longer quarterly session for deeper work.

Outside that window, set boundaries that make the rule easy to follow. Some partners turn off brokerage notifications during work hours or remove the app from their home screen. Others simply decide that market commentary is for the weekend. The aim is to make the default behavior match the rule, so that you are not relying on willpower alone.

Keep in mind that preparing for the window also saves time. A one-page list of holdings, with notes on why you own each, means a thirty-minute session can be spent on judgment instead of searching for information.

What does a sample week look like? An illustrative example

The following is an illustrative example, not a recommendation. Imagine a partner who has set Saturday morning as her portfolio hour. Through the week, she records all client work in the normal way and does not open her brokerage during working hours. Anything about her holdings that occurs to her goes on a single note on her phone labeled "Saturday."

On Saturday she works through the note, reads one company announcement from its primary source, checks whether any holding has drifted from her intended share of the portfolio, and writes a line in her decision record. Before putting the list away, she notes one question about a possible conflict with a client matter and sends it to the firm's compliance contact on Monday morning, before taking any step.

The result is a week in which billable time stayed billable, personal time stayed personal, and a potential issue got raised before it became a problem.

Should I keep a record of personal investing activity?

A simple log is a good idea. Note the date, a brief description of what you did and why, and the time you spent. It does not need to be elaborate. A few lines per session are enough.

The log serves several purposes. It shows, if ever needed, that personal activity happened outside client time. It supports any reporting your firm requires. And it improves your own decisions, because writing down your reasoning makes it harder to rewrite later.

Be careful that the log does not contain confidential client information. If a thought about a holding touches something you learned through your work, that is a signal to stop and consult compliance, not a detail to write down.

When should I involve an advisor or compliance contact?

Involve your compliance contact whenever the question is about what you are permitted to do: restricted lists, pre-clearance, holding periods or disclosure. Involve a qualified financial or tax professional when the question is about what makes sense for your finances, such as concentration, taxes or retirement planning. Working with advisors and self-directing are both legitimate approaches, and some partners use a mix, handling routine oversight themselves while consulting someone for structure.

Frequently Asked Questions

Can lawyers manage their own investments?

Generally yes, subject to their firm's policies and the professional rules in their jurisdiction. Restrictions often center on securities of clients and on confidential information, so check your firm's guidance before trading.

How do I keep personal investing separate from billable time?

Run them on separate clocks. Record only client work as billable, and schedule personal portfolio time outside working hours, for example in a weekly window. Removing prompts that pull you toward your brokerage during the day makes the separation easier to keep.

Do law firms restrict personal trading?

Many do, particularly where the firm represents public companies. Typical rules include restricted lists, pre-clearance and periodic reporting. Your firm's compliance office can tell you which apply to you.

How much time does a long-term portfolio need each week?

For long-term holdings, many self-directed investors find that around thirty minutes a week, plus a deeper quarterly review, is workable. The right amount depends on how many positions you hold and how often your circumstances change.
