Similar things unite with similar.

Explanation

(English-origin maxim.) Like things are to be grouped and treated together — the law joins similar matters and applies consistent rules to them.

Where this applies

• Two adjacent parcels owned by the same person are treated as a single tract for tax-assessment purposes because similar property naturally unites under one assessment.
• Claims arising from the same transaction are consolidated into one action because like causes of action belong together.
• Debts of the same kind owed to the same creditor are aggregated rather than treated separately.
