Its called the system of checks and balences.

The ultimate check on all three branches of government is the system of judicial review, where the judiciary has the power to interpret the constitution and determine the constitutionality of laws and actions taken by the executive and legislative branches. This ensures that all branches of government are acting in accordance with the constitution.
James Madison suggested several methods to check the powers of government. These include the separation of powers into three branches, checks and balances between the branches, federalism to divide power between the national and state governments, and a system of representative democracy to ensure accountability and prevent tyranny.
The separation of powers between the three branches of government is assured by having distinct roles for each branch. The three branches of government are executive, legislative and judiciary..
The separation of powers is the practice we use in the US national government to divide the national government's powers between the three branches (executive, legislative, judicial) so that the national government cannot abuse its powers. Each branch has certain powers and is able to "check" the other branches' powers to keep the three branches equal or "balanced". This system is known as the system of checks and balances and it is used to guarantee the separation of powers.
"Division of powers" or, more generally, "checks and balances."
There are not two branches of government, but rather three: the judiciary, executive, and legislative branches. This is to ensure a separation of powers so no one branch has more influence in government than the others.
Separation of Powers Separation of Powers
The system of checks and balances can create an adversarial relationship described as a "tug of war" between the different branches of government. This is because each branch is designed to have its own unique powers and responsibilities, and they often clash with one another in their interpretation and exercise of these powers. However, this adversarial relationship is intentional and necessary to prevent any one branch from accumulating too much power and to ensure a system of accountability and transparency.
The three branches of government share equal power in order for a fair governmental process. In addition, each branch of government has checks and balances on the other branches to ensure the separation of powers.
separation between powers is when the 3 branches are separated so no one brach has too much power
ensure that the powers of the separate branches overlap, so that each could better act as a check on the others.
