Quick answer: Before a deployment, the most important tasks are updating your legal documents including your will and power of attorney, ensuring your family has access to all financial accounts and knows how to manage them, reviewing your Servicemembers Group Life Insurance coverage, setting up automatic bill payments, and creating a household emergency plan. According to the Defense Finance and Accounting Service, only about half of service members have an updated will before deployment, which is the single most consequential administrative gap a family can face if something goes wrong. The full checklist below covers the four to six weeks before departure, the deployment period itself, and the often-overlooked homecoming phase.
Deployment preparation is the kind of task that feels like it can start tomorrow, right up until it cannot. The legal and financial pieces take longer than most service members expect, involve other people's schedules — attorneys, banks, insurance coordinators — and have consequences that extend far beyond the individual if left incomplete. This checklist is built for the service member and the family simultaneously, because deployment affects both and the preparation works better when both are involved.
A note before we begin: military family resources vary by branch, installation, and country. Where we reference specific programs, we note them as US-specific. If you are serving in another country's armed forces, the equivalent programs through your branch's family support services will apply. This guide is organizational support, not legal or financial advice. For specific legal documents, work with a JAG officer or military legal assistance office, which provides these services free of charge to service members.
What legal documents does a service member need before deployment?
This is the highest-stakes category in deployment preparation and the one most often treated as optional until it is not. Three documents matter most.
A will tells the legal system what you want to happen to your estate if you do not return. Without one, decisions are made by the courts according to state intestacy law, which may not reflect your wishes and which places your family in an extended legal process during an already devastating time. Military legal assistance offices on most installations prepare wills for service members free of charge, and many offer walk-in hours specifically to accommodate deployment timelines.
A general power of attorney authorizes your designated person — typically your spouse or a trusted family member — to make legal and financial decisions on your behalf while you are deployed. Without it, your family cannot handle legal matters that require your signature: selling a car, managing a lease, filing taxes jointly, or accessing certain accounts. A limited power of attorney restricts this authority to specific tasks if you prefer not to grant general authority.
A healthcare directive specifies your wishes for medical care if you are incapacitated and cannot communicate them. Paired with a healthcare power of attorney that designates someone to make medical decisions, these documents protect both your wishes and your family from having to make those decisions without guidance.
Get all three before departure. Schedule with JAG or military legal assistance at least three weeks before your deployment date, because their schedules fill quickly in the pre-deployment period.
What financial tasks should be completed before deployment?
Start with access. Every account your family may need to use during the deployment should be jointly accessible or accessible via power of attorney. This includes checking and savings accounts, investment accounts if applicable, and any accounts used for automatic bill payment. Do not wait for a financial emergency to discover an account only you can access.
Review and update your Servicemembers Group Life Insurance coverage. SGLI provides up to $500,000 in coverage for active duty service members at a low premium, and the beneficiary designation should reflect your current family situation. Changes in marital status, the birth of a child, or a family member's death may mean your current designation is outdated. Update it through your unit's administrative office.
Set up automatic payments for every recurring bill: mortgage or rent, utilities, car payments, insurance premiums, credit cards, and any subscriptions that matter. Then verify — after setting them up, check each one to confirm the payment method is current and the amount is correct. An automatic payment linked to an expired card does not pay the bill.
The financial buffer that experienced military families consistently recommend: three months of expenses in a readily accessible savings account that the family at home can draw on without involving the deployed service member. Deployment brings financial complications including delayed pay processing and unexpected expenses, and a buffer absorbs these without creating a crisis.
What home and household tasks matter before deployment?
Car maintenance is the one most families postpone and most regret. Service the vehicles that will be in use during the deployment before departure: oil change, tire pressure and tread check, brakes, and any overdue maintenance. A car breakdown is manageable stress when a partner is available to help. It is a significant logistical and financial problem for a spouse managing a household alone.
Create a home emergency contact list that covers the situations most likely to arise: a plumber, an electrician, the base or post emergency contact number, a trusted neighbor, and family members who can respond if needed. The family at home should know where the main water shutoff is, where the circuit breaker is, and how to contact the landlord or HOA if applicable. These feel like obvious things to communicate until they are needed and the information was never shared.
If you have children, prepare an updated medical information document for each child: their pediatrician's name and number, any medications and dosages, known allergies, and the name of the person authorized to make medical decisions if neither parent is reachable. Schools and medical providers may ask for written authorization for the non-deployed parent to make decisions independently.
What should the communication plan look like?
Realistic communication expectations matter more than many families acknowledge before a first deployment. Operational security restrictions, time zone differences, mission schedules, and connectivity limitations mean that regular contact is possible in some deployments and sporadic or impossible in others. Establishing realistic expectations before departure — rather than a specific schedule that cannot be kept — protects both the deployed service member and the family from the distress of a missed call becoming evidence of something worse.
Agree on a primary and a backup communication method. Email, a messaging app that works in low-bandwidth environments, and a scheduled window for video calls where connectivity allows are a common framework. Agree on what a gap in communication means and does not mean, and on who the family should contact through official channels if a genuine welfare check is needed.
For children, consider age-appropriate ways to maintain connection across the deployment: recorded bedtime stories, video messages, a shared journal, or a calendar that counts down in a way that makes time concrete for young children. The Office of the Deputy Assistant Secretary of Defense for Military Community and Family Policy publishes resources on supporting children through deployment, which military family support centers on most installations can provide.
What does homecoming preparation involve?
Homecoming is one of the most genuinely joyful moments in military family life and also one of the least practically prepared for, which is why the weeks after return are among the most stressful periods in the deployment cycle for many families. The adjustment is real on both sides and it takes time.
Practical homecoming preparation: do not plan anything elaborate for the first week. Return the house to a state you would be comfortable for your returning service member to see, handle any repairs or issues that were deferred during the deployment, and stock the kitchen with food and meals rather than planning a restaurant schedule that assumes more energy than the first week reliably delivers.
The adjustment period after return is documented and real. The Pew Research Center's research on military families found that a majority of veterans and military spouses report that the period of reintegration after deployment is one of the most challenging phases of military life, often more so than the deployment itself. Give the adjustment time, communicate about it, and use your installation's family support resources, which exist specifically for this phase.

Deployment preparation done well is a form of care — for your family, for your own peace of mind in the field, and for the relationship you are returning to. The checklist does not cover everything. It covers the things that, left undone, create the biggest problems. Start there, and work forward.
