The first step is creating a joint budget that takes into account both partner’s income sources, expenses, debts (if applicable), and savings targets (such as an emergency fund or retirement accounts), etc., This will help you set realistic expectations about what you can afford each month/year and ensure your spending is aligned with your long-term plans. It also provides the opportunity for open dialogue around money management which helps build trust between partners over time.

Once you have established a joint budget it’s important to focus on building up an emergency fund which should cover at least 3-6 months of living expenses in case either partner loses his/her job or other unexpected costs arise during this period of uncertainty. Additionally, depending on your risk tolerance, consider setting aside funds for longer-term investments such as stocks/bonds / mutual funds, etc., These investments may not yield immediate returns but could provide significant growth over time if managed properly. 

Despite having created budgets & savings plans, disagreements regarding money matters are inevitable – especially when one person feels like he/she has more control over the other over decision-making processes related to finance topics such as family vacations or large purchases. To prevent these disputes from escalating out of hand it is best practice to agree upon ground rules ahead of time - including who makes what decisions; how much input each party gets; whether there will be veto power granted by either side; etc,. Having clear boundaries upfront ensures everyone understands where they stand financially within the relationship thus helping minimize potential conflict later down the line  

 Setting achievable short - mid - long long-term financial objectives is essential when managing finances together since this gives both parties something tangible to work towards while providing motivation along the way too! Examples include paying off debt faster than planned; increasing monthly contributions towards retirement accounts; starting college funds for children etc,. Establish milestones throughout the process and track progress against them ensuring accountability from all sides!
